AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
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 correct?
(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 \(\left[\frac{2 J}{P}-1\right]\).
(d) The coefficient of restitution is \(\left[\frac{2 J}{P}+1\right]\).
- A Only (a) is correct.
- B (a) and (c) are correct.
- C (b) and (c) are correct.
- D Only (c) is correct.
