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

A$150$

B$3$

C$30$

D$300$

Solution

$\mathrm{F}=\frac{\Delta \mathrm{P}}{\Delta \mathrm{t}}=\frac{\mathrm{mv}-0}{0.1}$
$=\frac{150 \times 10^{-3} \times 20}{0.1}=30 \mathrm{~N}$
