Question

define perfectly inelastic collision

Answer 1

A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies together.

Answer 2

Hi...!!!
In Perfectly inelastic collision between two bodies the net kinetic energy changes and the vakue of e (coefficient of restitution) = 1

Hope this helps you....
