Is there any formula for inelastic collision??????????????
Suppose the masses of two bodies are m1 and m2 respectively. Also their initial speed be v1i and v2i respectively. While their final velocities be v1f and v2f respectively.
Coefficient of restitution is defined as ratio of relative speed of separation after collision and relative speed before collision, i.e.
@Vaisakh: Your equation is correct for perfectly inealastic collisions (e = 0), when two bodies stick together and move.
Hope you find it useful!
