A ball is moving with velocity 2m//s towards a heavy wall moving towards the ball with speed 1m//s as shown in figure. Assuming collision to be elastic, find the velocity of ball immediately after the collision.

A ball is moving with velocity 2m//s towards a heavy wall moving towards the ball with speed 1m//s as shown in figure. Assuming collision to be elastic, find the velocity of ball immediately after the collision.

A ball is moving with velocity 2m//s towards a heavy wall moving towards the ball with speed 1m//s as shown in figure. Assuming collision to be elastic, find the velocity of ball immediately after the collision.

A wall moving with velocity 2 cms^(-1) towards the ball and ball is moving towards the wall with a velocity 10 cms^(-1) . It hits the wall normally and makes elastic collision with wall. The velocity of ball after collision with wall in cms^(-1) .

A ball of mass m moving with speed v towards the right strikes a wall moving towards the left with speed u . Find the change in the K.E. of the ball if the collision is elastic.

The two balls shown in figure are identical the first ball is moving at a speed v towards right and the second staying at rest. The wall at the extreme right is fixed. Assume all collisions to be elastic. Show that the speeds of the balls remain unchanged after all the collisions have taken place.

Two particles of equal mass moving towards each other with velocities 20 m*s^(-1) and 30 m*s^(-1) collide. If the collision is elastic, find their velocities after the collision.
