Two balls each of mass `'m'` are moving with same velocity `v` on a smooth surface as shown in figure. If all collisions between the balls and balls with the wall are perfectly elastic, the possible number of collisions between the balls and wall together is

In an elastic collision between smooth balls :

Rod can rotate about hinge point 'P'. A ball of mass 'm' is projected with a velocity 5v_(0) in a gravity free space as shown in figure. Collision between the rod and the ball is perfectly elastic. Then find the magnitude of velocity of ball after the collision ( neglect the friction between the ball and the rod during the collision ).

Two balls marked 1 and 2 of the same mass m and a third ball marked 3 of mass M are arranged over a smooth horizontal surface as shown in the figure. Ball 1 moves with a velocity v_(1) towards ball 2. All collisions are assumed to be elastic. If Mltm , the number of collisions between the balls will be.

A sphere of mass m slides with velocity v on as frictionless surface towards a smooth inclined wall as shown in figure. If the collision with the wall is perfectly elastic find a. the impulse imparted by the wall on the sphere b the impulse imparted by the floor on the sphere.
