Question

A cricket ball of mass 100g moving with a speed of 30m/s is brought to rest by a player in 0.03second find change in momentum of ball

Answer 1

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

Answer 2

-100N is rhe correct answer of this equation
