# M2 Collisions Qs Ex 4B qs 8 heinemann book watch

1. A sphere of mass m1 moving with speed u1 collides directly with a similar sphere of mass m2 moving with speed u2 in da same direction. (u1>u2). The coefficient of restitution between two spheres is e. Show that the loss of KE (E) due to the collission satisfies the equation

2(m1+m2)E= m1.m2(u1-u2)^2(1-e^2)

the equation is crazy huh?
2. This one's been around a few times before. There's a lot of working out involved. If you want the solution, search this forum for "killer question".
