1 Session 12 Lab Based Questions Free Response: 1. You are conducting an experiment to measure the acceleration due to gravity g u at an unknown location. In the measurement apparatus, a simple pendulum swings past a photogate located at the pendulum's lowest point, which records the time t 10 for the pendulum to undergo 10 full oscillations. The pendulum consists of a sphere of mass m at the end of a string and has a length l. There are four versions of this apparatus, each with a different length. All four are at the unknown location, and the data shown below are sent to you during the experiment. t 10 (cm) (s) T (s) a. For each pendulum, calculate the period T. Use a reasonable number of significant figures. Enter these results in the table above. b. On the axes below, plot the period versus the length of the pendulum. What does the graph suggest about the relationship between the length of the pendulum and its period? The graph shape suggests that the relationship between period and length is not linear because the graph looks like a square root graph. T 2 = (slope)l c. What two quantities should be graphed to give a linear relationship? Put those values into the blank column in the table above. T 2 vs, L
2 d. On the axes below, plot the terms in part (c). Draw a best-fit straight line for this data. Does not have to pass through the orgin (but its ok if it does). Does not have to pass through every point just has to pass average e. Assuming that each pendulum undergoes small amplitude oscillations, from your fit determine the experimental value gexp of the acceleration due to gravity at this unknown location. Justify your answer. f. If the measurement apparatus allows a determination of gu that is accurate to within 4%, is your experimental 2 value in agreement with the value 9.80 m/s? Explain fully.
3 2. The figure above represents a racetrack with semicircular sections connected by straight sections. Each section has length d, and markers along the track are spaced d/4 apart. Two people drive cars counterclockwise around the track, as shown. Car X goes around the curves at constant speed v c, increases speed at constant acceleration for half of each straight section to reach a maximum speed of 2v c, then brakes at constant acceleration for the other half of each straight section to return to speed v c. Car Y also goes around the curves at constant speed v c, increases speed at constant acceleration for one fourth of each straight section to reach the same maximum speed 2v c, stays at that speed for half of each straight section, then brakes at constant acceleration for the remaining fourth of each straight section to return to speed v c. (a) On the figures below, draw an arrow showing the direction of the net force on each of the cars at the positions noted by the dots. If the net force is zero at any position, label the dot with 0. (b) i. Indicate which car, if either, completes one trip around the track in less time, and justify your answer qualitatively without using equations. Car y completes the trip faster. Car x accelerates from vc to 2vc over half of the straight away, then immediately begins to slow back down and reaches vc over the other half of the straight away. Car x only travels at 2vc for an instant before it slows does. For the entire straight away, its average velocity is less than 2vc. Car y accelerates from vc to 2vc over just a quarter of the straight away. It then travels at 2vc for half of the straight away before slowing down to vc for the last quarter. Car y has a higher average speed because it travels at 2vc for a greater distance on the straight aways. Because each car has the same speed on the curves, car y completes the trip In less time. ii. Justify your answer about which car, if either, completes one trip around the track in less time quantitatively with appropriate equations.
4 3. A world-class runner can complete a 100 m dash in about 10 s. Past studies have shown that runners in such a race accelerate uniformly for a time tu and then run at constant speed for the remainder of the race. A worldclass runner is visiting your physics class. You are to develop a procedure that will allow you to determine the uniform acceleration au and an approximate value of tu for the runner in a 100 m dash. By necessity your experiment will be done on a straight track and include your whole class of eleven students. (a) By checking the line next to each appropriate item in the list below, select the equipment, other than the runner and the track, that your class will need to do the experiment. Stopwatches Tape measures Rulers Masking tape Metersticks Starter s pistol String Chalk (b) Outline the procedure that you would use to determine au and tu, including a labeled diagram of the experimental setup. Use symbols to identify carefully what measurements you would make and include in your procedure how you would use each piece of the equipment you checked in part (a). Place tape at 1 m intervals near the beginning of the track, starting at 0 and going to 10 m using the tape measure. Place a student with a stopwatch at 2m, 3m, 4m, 5m, 6m,7m, 8m, 9m, and 10 m [9 students]. Using a tape measure, mark at 80 m and 100m, place students with stopwatches at each one. One student, holding both then gun and a stopwatch, will shoot the starter s pistol and all students will begin their watches and the runner will begin. Each student will stop as the runner passes them. Record data. Make a graph.
5 (c) In a clear, concise paragraph, outline the process of data analysis, including how you would identify the portion of the race that has uniform acceleration, and how you would calculate the uniform acceleration. By graphing the data points, we see a curved part of the graph for the first few meters this curve indicates that the runner is accelerating (curved lines on x vs t represent acceleration). Sketch the curve to it our data. The last two data points indicate constant velocity. Drawing a line through those data points and tracing it back to the beginning of the graph will intersect with the curved part of the graph. That intersection represents the time that the runner went from accelerating to moving at a constant velocity. This is t u that we need. We now know the constant final velocity of the runner (from the slope of the straight part of the graph), the initial velocity (0) and the time for which he was accelerating. We can find a u by taking the change in velocity and dividing it by the time.
6 4. A group of students has two carts, A and B, with wheels that turn with negligible friction. The carts can travel along a straight horizontal track. Cart A has known mass ma. The students are asked to use a one dimensional collision between the carts to determine the mass of cart B. Before the collision, cart A travels to the right and cart B is initially at rest, as shown above. After the collision, the carts stick together (a) Describe an experimental procedure to determine the velocities of the carts before and after a collision, including all the additional equipment you would need. You may include a labeled diagram of your setup to help in your description. Indicate what measurements you would take and how you would take them. Include enough detail so that another student could carry out your procedure. Initial velocity of cart A Velocity of cart a is determined by finding the distance it travels over the time it takes to do so. Push cart A, have it pass over a clearly marked distance of 1m. Time how long it takes cart to pass over that distance. Calculate the velocity of cart A. Final velocity of both carts Final velocity will be constant. Mark a 1 m distance behind cart B. Measure the time that it takes the cart a and b combination to move that distance and calculate the velocity. Alt: Use a motion detector behind cart a to measure the distance as a function of time. Graph d vs. t. The slopes of the graph will the velocities.
7 A group of students took measurements for one collision. A graph of the students data is shown below. (c) Given m A = 0.50 kg, use the graph to calculate the mass of cart B. Explicitly indicate the principles used in your calculations. The slope of a line on a d vs t graph is the velocity. Draw 2 lines one for cart a by itself, and one for the combination. Find the slope, it will be the initial and final velocities. In the conllision, momentum was conserved the total momentum of cart a is equal to the total momentum of cart a and b.
8 (d) The students are now asked to consider the kinetic energy changes in an inelastic collision, specifically whether the initial values of one of the physical quantities affect the fraction of mechanical energy dissipated in the collision. How could you modify the experiment to investigate this question? Be sure to explicitly describe the calculations you would make, specifying all equations you would use (but do not actually do any algebra or arithmetic). Initial values: v a, m a, m b Pick a value, change it, note the initial and final velocities.
