The force is given by the rate of change of linear momentum of the ball, which comes to rest on the player's hand. Thus,

\displaystyle\longrightarrow\sf{F=-\dfrac{150\times10^{-3}(0-20)}{0.1}}

\displaystyle\longrightarrow\sf{F=-150\times10^{-3}\times-20\times10}

\displaystyle\longrightarrow\sf{\underline{\underline{F=30\ N}}}

\huge{\underline{\sf{Answer:-}}}

\boxed{\sf{F = 30 N}}

\huge{\underline{\sf{Explainationtion:-}}}

Given:-

  • Mass of cricket ball, m = 150 g = 0.15 kg

  • Initial velocity of the ball, u = 0

  • Final velocity of the ball, v = 20 m/s

  • Time taken in the catching process, t = 0.1 s    

→ F = ma

→ m × (v - u)/t

→ F = 0.15 kg × 20 - 0 / 0.1

\boxed{\sf{F = 30N}}

The force of the blow exerted by the ball on the hand of the player is equal to 30N.

Hence, this is the required solution.
