Question

2. The negative ratio of relative
velocity of separation to relative velocity of approach is called
a) eastatc collision
b) Incastle collision
c) coefficient of restitution
d) head on collision​

Answer 1

Answer:

Coefficient of restitution (COR)

The coefficient of restitution (COR), also denoted by (e), is the ratio of the final to initial relative velocity between two objects after they collide. ... A perfectly inelastic collision has a coefficient of 0, but a 0 value does not have to be perfectly inelastic.
