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

Options

  1. A1.5 Mv
  2. B2 Mv
  3. Czero
  4. DM v

Correct answer

B. 2 Mv

Step-by-step solution

Impulse aligned |J| & =| p| & =M v-(-Mv) & =2 Mv aligned
