Question

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?
A. `(2J)/(p) -1`
B. `(2J)/(p) +1`
C. `(J/p) + 1`
D. `(J/p)-1`

Answer 1

Correct Answer - A
`e = (RSOS)/(RSOA) = (J+(J-p))/p=(2J)/p-1`
