Question

a cricket ball of mass 150g is moving at a speed of 25m/s is brought to rest by a player in 0.03 s. find the average force applied by the player..​

Answer 1

Answer:

125 N

Step-by-step explanation:

mass=150g or 0.15kg

given

u =25m/s

v = 0

time =0.03

Acceleration = v -u /t

a=2500/3

force=mass×acceleration

=0.15kg×2500/3

=125 N

Answer 2

Answer:

Mass, m = 150g = 0.15kg

Speed, v = 25m/s

Time, t = 0.03sec

So

=> F = ma

To find a (acceleration) we use

=> a = v/t

=> a = 25/0.03

=> a = 833.34 $m/{s}^2$

Now to find Force we use

=> F = ma

=> F = 0.15kg × 833.34$m/{s}^2$

=> F = 125N
