Impulse & Momentum Conservation

A body of mass M hits normally a rigid wall with velocity V and bounces back with the same velocity. The impulse experienced by the body is

Show answer and solution

Answer: (c)

Impulse $= \Delta p = MV - (-MV)$ (the velocity reverses).
$J = 2MV$
So the answer is (c) 2MV.
