Two billiard balls each of mass 0.05 kg moving in opposite directions with speed `6 m s^-1` collide and rebound with the same speed. What is the impulse imparted to each ball due to the other ?

Two solid subber balls A and B having masses 0.2 and 0.4 are moving in opposite directions with velocity of A equal to 0.3 ms^-1 After collission, the two balls come to rest when the velocity of B is

A police van moving on a highway with a speed of 30 km h^-1 fires a bullet at a thiefs car speeding away in the same direction with a speed of 192 km h^-1 . If the muzzle speed of the bullet is 150 m s^-1 with what speed does the bullet hit the thiefs car ? (Note: Obtain that speed which is relevant for damaging the thief s car).
