Question

The coefficient of restitution 'e' for a perfectly inelastic collision is

Options:

A . 1

B . 0

C . ∞

D . -1

Answer: Option B
:
B
Coefficient of restitution is the ratio between Relative velocity of separation to Relative velocity of approach of colliding bodies.
In perfectly inelastic collision, the two bodies stay togethere after collision and hence the relative velocity of separation is zero.
Therefore, coefficient of restitution is zero.
