Question

A cricket ball of mass 250 g collides with a bat with velocity 10 m/s and returns with the same velocity within 0.01 second. The force acted on bat is:

• A. 25 N
• B. 50 N
• C. 250 N
• D. 500 N

Answer 1

The correct option is D 500 N

$u=10\frac{m}{s}$

$v=-10\frac{m}{s}$

mass $m=0.25kg$

time $t=0.01s$

from $v=u+at⟹20=at⟹a=\frac{20}{t}=\frac{20}{0.01}=2000\frac{m}{s^2}$

from $F=ma⟹F=0.25\times 2000=500N$
