A ball is projected from ground with velocity u at an angle β with horizontal towards a smooth vertical wall which is also approaching towards the ball with velocity v. The ball makes an elastic collision with the wall and comes to the point of projection. Find time interval between projection and impact with the wall. Advanced problems Playlist
