If there is a particle X of mass 3m which is moving with velocity Ui on a smooth horizontal table and it collides with a particle Y of mass 5m which is at rest (and we are given that the coefficient of restitution between the particles is e, then how can I find the velocities of X and Y immediately after the collision in terms of e and u?
Also is there a way of showing the speed of X immediately after the collision does not exceed 3u/8 for all values of e?
Depending on your result for , you may get a negative answer which will mean that the particle has changed direction. This implies that you can produce an inequality where and when solved you should get it to show that it does not exceed
