Answer and Explanation:
A fielder or a cricketer lowers his hand while catching a ball that is hit by the batsman so that, the force exerted by the ball is lowered
When the ball is coming towards the fielder, it has some velocity that is it has momentum
Momentum = Mass * Velocity
p = mu
We know that,
Force = Change in momentum / Time
F = Δp/Δt
If the fielder does not lower his hand the velocity of the ball becomes 0
Hence,
F = (mu - 0)/t
F = mu/t
If the fielder lowers his hand, the velocity is reduced to v and its momentum is reduced to mu
Hence,
F' = (mu - mv)/t
F' = m(u - v)/t
Since, F' < F
the force experienced by cricketer when he lowers his hand is less
