Question

an object of mass 50 kg is accelerated uniformly from a velocity of 4m/s to 8m/s in 8s . calculate the intial and final momentum of the object. also find the magnitude of the force exerted on force​

Answer 1

initial momentum = 200 kg m/s

final momentum = 400 kg m/s

so change in momentum = 200 kg m/s

this change has occurred in 8 seconds.

so F = 200/8 = 25 N

Answer 2

Explanation:

p=ma

u=200

v=400

f=200
