Question

A cricketer catches a ball of mass 150 gm in 0.1 sec moving with speed 20 m/s, then he experiences force of

• A. 300 N
• B. 30 N
• C. 3 N
• D. 0.3 N

Answer 1

Answer: (B)

30 N

Answer 2

Impulse = Change in momentum
$F\cdot ?t=m\cdot v$;
$F=\frac{m\cdot v}{?t}=\frac{150\times10^{-3}\times20}{0.1}$
$=30N$.
