Question

A cricket ball of mass 250g 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

Answer: (D)

500 N

Answer 2

Force $= m\mspace{6mu}\left( \frac{dv}{dt} \right) = \frac{0.25 \times \lbrack(10) - ( - 10)\rbrack}{0.01} = 25 \times 20 = 500\mspace{6mu} N$
