2. The radius of a wheel is 7 m. What is the displacement of point P, on the wheel (just on the ground) during the half rotation of wheel? The half of the distance travelled by a car with 15 ms^{-1} and the 2^{nd} half with 30 ms^{-1}. Calculate the average speed of the car. (3+2)

3. Show that, if the speed of a car is doubled then the braking distance is four times. If action reaction forces are equal and opposite then why a body moves? An athlete takes 40 s to cover a circular path of radius R. What is the ratio of distance to displacement of him for 2 minutes 20 second? (2+1+2)

4. A ball of mass 100 g rebounds a vertical wall with same speed . If the time of collision is 0.05 s then calculate the force acting on the ball by the wall. Write two difference between circular motion and rotational motion. Plot displacement versus time graph of a particle freely falling under gravity. (2+2+1)

5. What is the physical quantity is defined by Ns? A body is moving with uniform speed has uniform velocity. Is it true? Explain. A particle starting from rest moving with uniform acceleration and after 5 s it’s speed is . Next 5 s it is moving with uniform speed and last 4 s it is moving with uniform acceleration and become finally rest. Plot velocity versus time graph and calculate total distance travelled by it from graph. (1+1+3)

8. Give one example that speed of a body remain same but it has acceleration. When a bullet is fired on a glass window it makes a hole but it breaks when a stone is thrown. Explain why? Why a man falling from a certain height receives more injury when he falls on a marble floor than when he falls on a heap of sand? (1+2+2)

9. Is it possible that a particle has velocity in two directions but it has acceleration in one direction? Explain it. A pendulum is suspended from the roof of a car which is moving with constant speed. What change in position of pendulum you observe in this case? Why the centripetal and centrifugal forces are called real and pseudo force respectively? (2+1+2)

10. Which factor provides centripetal force to move a car in circular path? A ball is dropped from a height what is the ratio of distance travelled by it in 1^{st}, 2^{nd} and 3^{rd} second of its motion? In tug of war two person apply T amount of force to each other. What is the tension acting on the rope? (1+3+1)
