CONCEPT:

  • Perfectly elastic collision: A perfectly elastic collision is defined as one in which there is no loss of kinetic energy and momentum of the system is conserved  in the collision.
  • Inelastic collision: A inelastic collision is defined as one in which there is a loss of kinetic energy and momentum of the system is conserved in the collision.
  • Coefficient of restitution is the ratio of relative velocity after impact to the relative velocity before impact. 

Coefficient of restitution (e)

  • For perfectly elastic collision, e = 1
  • For inelastic collision, e < 1
  • For a perfectly inelastic collision,e = 0

 

EXPLANATION:

As from the above discussion, we can say

  • The coefficient of restitution for perfectly inelastic bodies is: e = 0

​So option 1 is correct.
