A ping-pong ball strikes a wall with a velocity of `10 ms^(-1)`. If the collision is perfectly elastic, find the velocity if ball after impact

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 10 kg is moving with a velocity of 10 m / s . It strikes another ball of mass 5 kg which is moving in the same direction with a velocity of 4 m / s . If the collision is elastic, their velocities after the collision will be, respectively

If a ball strickes with a velocity u_(1) at the wall which itself is approaching it with a velocity u_(2) then find the velocity of the ball after collision with the wall.

If a ball strickes with a velocity u_(1) at the wall which itself is approaching it with a velocity u_(2) then find the velocity of the ball after collision with the wall.

Two identical balls collide head on. The initial velocity of one is 0.75 ms^(-1) , while that of the other is -0.43 ms^(-1) . If the collision is perfectly elastic, then their respective final velocities are

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.
