The correct Answer is:
`(3)`
Ball(2) with wall - 1st (Ball 2 rebounds)
Ball 2 with wall 1 -2nd (Both balls rebounds)
Ball 2 with wall 1 -3rd (Ball 2 rebounds)

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.

Velocity of the ball A after collision with the ball B as shown in the figure is (Assume perfectly inelastic and head - on collision)

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.

A ball of mass m moving with velocity vecu = u_(x) hati + u_(y) hatj hits a vertical wall of infinite mass as shown in the figure. The ball slips up along the wall for the duration of collision and there is friction between the ball and the wall. Neglect the effect of gravity. Pick up the correct alternative.

Two balls of masses m each are moving at right angle to each other with velocities 6 m/s and 8 m/s respectively. If collision between them is perfectly inelastic, the velocity of combined mass is
