A ball of mass `m` is moving normally towards a walll of mass `M(gt gt m)` with the velocity `4 m//s`. The wall is also moving. After striking elastically with the wall , velocity of ball becomes `8 m//s`. Find the speed of the wall:

A ball of mass m moving with velocity v_(0) collides with a wall as shown in Fig. After impact it rebounds with a velocity' (v_(0))//2 The component of impulse acting on the ball along the wall is

A ball of mass m moving with velocity v_(0) collides with a wall as shown in Fig. After impact it rebounds with a velocity' (v_(0))//2 The component of impulse acting on the ball along the wall is

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' moves normal to a wall with a velocity 'u' and rebounde with the same speed. The change in momentum of the ball during the rebounding is

A ball of mass m approaches a heavy wall of mass M with speed 4 m/s along the normal to the wall. The speed of wall before collision is 1m/s towards the ball. The ball collides elastically with the wall. What can you say about the speed of the ball after collision? Will it be slightly less than or slightly higher than 6 m/s ?
