A body A moving with momentum ‘P' collides one dimensionally with another stationary body B of same mass. During impact. A gives impulse ‘ J' to B. Then which of the following is/are collect?
a) The total momentum of A and B is ‘P’ before and after impact and (P - J) during the impact.
b) During the impact. B gives impulse of magnitude J to A.
c) The coefficient of restitution is [
