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

Options

  1. A1.5Mv1.5 \mathrm{Mv}
  2. B2Mv2 \mathrm{Mv}
  3. Czero
  4. DMvM v

Correct answer

B. 2Mv2 \mathrm{Mv}

Step-by-step solution

Impulse ∣J∣=∣Δp∣=Mv−(−Mv)=2Mv\begin{aligned} |J| & =|\Delta p| \\ & =M v-(-Mv) \\ & =2 Mv \end{aligned}
