A particle of mass m moving with speed u makes a head-on collision with an identical particle which is initially at rest. The particles coalesce and move off with a common velocity. (a) Find the common speed of the particles after the collision. (b) Find the ratio of the kinetic energy of the system after the collision to that before it. (c) What happens to the kinetic energy that is 'lost'?
