In a one-dimensional collision between two identical particles. A and B, B is stationary and A has momentum `p` before impact. During impact, B gives an impulse J to A. Find the coefficient of restitution between A and B?

Text Solution

Verified by Experts

The correct Answer is:
A, B
`J="impulse"="change in momentum"`
`e=(RVOS)/(RVOA)`

`=((J//m)+(J-P//m))/((P//m))`
`=(2J)/(P)-1`
