Question

a car weighing 1600kg moving with a velocity of 30m/s retards
uniformly coming to rest in 20s calulate the a)initial momentum of
the car b)final,momentum of the car c)rate of change of momentum
d)acceleration of the car e)magnitude of the force applied?

Astha · Answer

A Initial momentum= u x m that is 1600 x30=48000kg m/s

B Final momentum = v x m = 0 x 1600=0kg m/s
