1 Physics 02_16 Remediation Packet Name A toy rocket was launched into the air from ground height. After the rocket reached its maximum height, it fell back to Earth. As it was falling, data was recorded about its velocity. At some point as the rocket fell, a parachute opened to slow its fall and protect the rocket as it reached the ground. 1. Plot an appropriate graph and draw a smooth curve that passes through each point. Time (s) Velocity (m/s) a. Label the following parts of the squirrel s descent: Positive acceleration Negative acceleration Terminal velocity b. Create a force diagram for the rocket at each of the time intervals below. a. t= 2 seconds. b. t= 6 seconds c. t=14 seconds d. t=22 seconds c. Your teacher wants to know how fast the rocket will be going at exactly x seconds. Using the equation a = v t solve for v f. d. In addition to knowing how fast it will be going, your teacher wants to know how far it will have fallen after t seconds. Using the equation x = v i t at2, solve for t. 2. What is meant by unbalanced forces, and what is the result? Draw free body diagram that represents this. 3. What is meant by balanced forces, and what are the possible results? Draw a free body diagram for each possible result.

2 4. Create a force diagram and context for each of the descriptions below. a. moving to the left, slowing down e. moving to the left, speeding up b. moving to the right, slowing down f. moving the to the right, speeding up c. moving upwards, slowing down g. moving upwards, speeding up d. moving downwards, slowing down h. moving downwards, speeding up 5. For each of the force diagrams below create a context, describe the net force in both the horizontal and vertical directions, and describe acceleration of the object. 6. For each of the force diagrams below compare the following criteria: a. The net force in the horizontal directions b. The net force in the vertical direction: c. The acceleration of the object. 60N 0.5N N 3.5N 60N 0.5N 7. Dump truck has a maximum carrying capacity of kg. What is the maximum weight the truck is capable of carrying? 8. What is the force applied by a 10,000kg jet as it accelerates from rest to 90 m/s over 15 seconds?

3 9. What is the force applied by a 400kg car as it accelerates from rest to 20 m/s over 5 seconds? 10. During 5 th period Dylan resisted the forces applied by her classmates in a tug-of-war competition. 6 classmates took on Dylan, each applying a force of 400N. a. How much force was Dylan pulling back with? b. How many people would it take to pull Dylan if she can withstand a force of 30,000N? 11. A car can go from 0 m/s to 27 m/s in 4.5 seconds. a. If a net force of 6600 N acted on the car, what is its mass? b. If a 600N force is applied to the car, what is the resulting acceleration of the car? c. How long would it take for the car to come to a stop over a distance of 100m? 12. Comparing the concepts of mass and weight, one is basic fundamental depending only on the internal makeup of an object and the number and kind of atoms that compose it. The concept that is fundamental is (mass) (weight). 13. The concept that additionally depends on location in a gravitational field is (mass) (weight). 14. (Mass) (Weight) is a measure of the amount of matter in an object and only depends on the number and kind of atoms that compose it. 15. (Mass) (Weight) is related to the gravitational force acting on the object. 16. (Mass) (Weight) depends on an object s location, whereas (mass) (weight) does not. In other words, a stone would have the same (mass) (weight) whether it is on the surface of Earth or on the surface of the moon. However, its (mass) (weight) depends on its location. 17. On the moon s surface, where gravity is only about one sixth of Earth gravity (mass) (weight) (both the mass and the weight) of the stone would be the same as on Earth.

4 18. Calculate the weight of a 82 kg person on the following celestial bodies: a. Moon Celestial Body Acceleration due Mass of Celestial to gravity (m/s/s) Body (kg) b. Jupiter Earth x Moon x Jupiter x c. Earth 19. Calculate the mass of a N person on the following celestial bodies: a. Moon b. Jupiter c. Earth 20. Describe the relationship between mass of a celestial body and the acceleration due to gravity on that celestial body 21. Describe the relationship between the weight (force) of an object on a celestial body and the acceleration due to gravity on that celestial body. 22. Describe the relationship between mass of a celestial body and the weight (force) of an object on that celestial body. 23. Referring to the data table that displays the acceleration due to gravity and mass of each celestial body, describe one way to increase the amount of acceleration due to celestial body.

5 Velocity (m/s) A 1.0 kg book is sliding to the right across a table. a. Create a free body diagram to represent this situation at the following times: Acceleration of Book b. Explain why the net force in the y-axis is zero Newtons. c. Explain why the acceleration of the object in the y-axis is zero m/s/s Time (seconds) d. What is the direction of the acceleration at the following times: e. What is the acceleration of the object in the x-axis at the following times: f. What is the net force on the object in the x-axis at the following times:
