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)

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? Â (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)
