Question

Calculate the change in momentum of a body weighing 5000 gm when its velocity increases from 2m/s to 4m/s plzz answer irs urgent

Answer 1

5000gm =5kg
v1 = 2m/s
v2 = 4m/s

Momentum in 1st case = m×v1 = 10kgms^-1
Momentum in 2nd case = m× v2 = 20kgms^-1

Change in momentum = 20 - 10 = 10kgms^-1

Hope that helps:))

Answer 2

Mass =5000g =5 kg V =4 m/s U =2m/s Rate in change of momentum = M (v-u)  5 (4-2) 5*2 =10 kg m per s
