A player caught a cricket ball of mass 150 g150 \mathrm{~g} moving at a speed of 20 m/s20 \mathrm{~m} / \mathrm{s}. If the catching process is completed in 0.1 s0.1 \mathrm{~s}, the magnitude of force exerted by the ball on the hand of the player is:

Options

  1. A3 N3 \mathrm{~N}
  2. B300 N300 \mathrm{~N}
  3. C150 N150 \mathrm{~N}
  4. D30 N30 \mathrm{~N}

Correct answer

D. 30 N30 \mathrm{~N}

Step-by-step solution

F=ΔPΔt=mv−00.1=150×10−3×200.1=30 N\begin{aligned} & \mathrm{F}=\frac{\Delta \mathrm{P}}{\Delta \mathrm{t}}=\frac{\mathrm{mv}-0}{0.1} \\ & =\frac{150 \times 10^{-3} \times 20}{0.1}=30 \mathrm{~N}\end{aligned}
