A particle of mass m moving at a velocity v strikes with the wall at an angle alpha with the wall and leaves ball making same angle with the wall. Choose the correct statemet (s) from the following.

A metal ball hits a wall and does not rebound whereas a rubber ball of the same mass on hitting the wall the same velocity rebounds back. It can be concluded that–

A metal ball hits a wall and does not rebound whereas a rubber ball of the same mass on hitting the wall the same velocity rebounds back. It can be concluded that–

A lead ball and rubber ball having same mass, strike normally on a smooth vertical wall with the same velocity. The lead ball falls down after striking but the rubber ball bounces back. Then

A ball of mass 0.5 kg moving with a velocity of 2 m//s strikes a wall normally and bounces back with the same speed . If the time of contact between the ball and the wall is 1 millisecond , the average force exerted by the wall on the ball is
