Answer 2

Given :-

A cricket ball of mass 150g moving at a speed of 25 ms^-1 is bought to rest by a player in 0.03s

To Find :-

Average force

Solution :-

We know that

v = u + at

0 = 25 + a(0.03)

0 - 25 = 0.03a

-25 = 0.03a

-25/0.03 = a

-2500/3 = a

Now

1 kg = 1000 g

150 g = 150/1000 = 0.15 kg

F = ma

F = 0.15 × -2500/3

F = 15/100 × (-2500)/3

F = -125 N
