Revise A) Number system B) Polynomials PHYSICS Q1. The following paragraph compares the performance of a magnetically levitated train (thetransrapid) to a conventional high speed passenger train (the ICE). The Transrapid is not only fast, but it can also accelerate quickly to high speeds 300 km/h (185 mph) can be reached after a distance of only 5 km (3 miles). Modern high-speed trains require more than 28 km (18 miles) and at least four times as long to reach the same speed. How does the acceleration of the Transrapid compare to the acceleration of the ICE? Q2. Cars cruise down an expressway at 25 m/s. Engineers want to design an interchange for a deceleration of 2.0 m/s2 over 3.0 s. (a) What velocity will cars have at the end of the approach? (b) What minimum approach length will satisfy these requirements? (c) What maximum velocity could a car entering the interchange have and still be able to exit at the intended velocity? (Assume an extreme deceleration of four times the usual rate)

Q3.The exercise consists of three small and one large velocity-time graph. Complete the three small velocity-time graphs from the information provided below each graph.

Whenever possible, calculate the acceleration of the object as well. Problem Solving Assessment 1.

3 Q3.The exercise consists of three small and one large velocity-time graph. Complete the three small velocity-time graphs from the information provided below each graph. The larger velocity-time graph shows the motion of some hypothetical object over time.break the graph up into segments and describe qualitatively the motion of the object in each segment. Whenever possible, calculate the acceleration of the object as well. Problem Solving Assessment 1. When a person on the earth is observing a lunar eclipse (eclipse of the moon), an astronaut on the moon, facing the earth, will observe an eclipse of (a) the Sun (b) the Moon (c) The Earth (d) he will not observe any eclipse. 2. Shown here is an autorickawmeter.to calculate the fare, the meter uses one of thefollowing.which one could it be? (a) the milestones on the road (b) the amount of petrol used up. (c) the maximum speed reached (d) the number of wheels rotations. 3. In Delhi,Bankimis running in the north- easterly direction

and casts a shadow on the ground due to the Sun s light as shownbelow.what could be the time of the day when this happens? (a) 10.30 AM (b) 1.30 PM (c) 4.

4 and casts a shadow on the ground due to the Sun s light as shownbelow.what could be the time of the day when this happens? (a) AM (b) 1.30 PM (c) 4.30 PM (d) this is never possible. 4. In a deep valley on Earth, a person shouting will hear an echo as the sound Is reflected back off the surrounding mountains. In a similar valley on the Moon, no echo will be heard. This is because (a) the gravitational pull on the moon is too low (b) the temperature on moon is too low. (c)there is no air on the moon for the sound to travel through. (d)the mountains on the moon cannot reflect sound. 5. Which of the following is true about static charges? (a) They accumulate mostly on poor conductors of electricity. (b) They accumulate mostly on good conductors of electricity. (c) They accumulate both on good and poor conductors of electricity. (d) They do not accumulate on surfaces, but are found in the air during winter. 6. The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero? Justify you answer. 7. How will the equations of motion for an object moving with a uniform velocity change? 8. A car starts from rest and moves along the x-axis with constant acceleration 5 ms 2 for 8 seconds. If it then continues with constant velocity, what distance will the car cover in 12 seconds since it started from the rest? 9. A motorcyclist drives from A to B with a uniform speed of 30 km h 1 and returns back with a speed of 20 km h 1. Find its average speed. 10. An object is dropped from rest at a height of 150 m and simultaneously another object is dropped from rest at a height 100 m. What is the difference in their heights after 2 s if both the objects drop with same accelerations? How does the difference in heights vary with time? 11. An object starting from rest travels 20 m in first 2 s and 160 m in next 4 s.what will be the velocity after 7 s from the start. 12. Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between 4th and 5th seconds.
