Momentum and CollisionHard

Question

In a one dimensional collision between two identical two identical A and B, B is stationary and A has momentum p before impact. During impact. B gives impulse J to A.

Options

A.The total momentum of the ‘A’ plus ‘B’ system is p before and after the impact, and (p - 1) during the impact.
B. During the impect A gives impules J to B
C.The coefficient of restitution is - 1
D.The coefficient of restitution is - 1

Solution


For A : P - J mv1 .....(i)
For B : J = mv2.....(ii)
∴ e = - - 1
