Question

a cricket ball of mass 100g moving with a speed of 30m/s is brought to rest by a player in 0.03s.find
1)the change in momentum of the ball
2) average force applied by the player

Answer 1

here is your answer... please check it...

Answer 2

Answer:

hey mate!

Explanation:

I guess the question is the rate of change in momentum

Mass= 0.1 kg

Initial Momentum= m*speed (u)=0.1*30= 3

Final Momentum= m* rest (v)= 0.1*0 = 0

Change in Momentum= Final-Intial = 0-3 = -3

Rate of change in momentum= (change in momentum)÷time taken  

                                              = (-3)÷0.03

                                              = -100
