Question

A body of mass 6kg is acted on by a force so to that it's velocity change from 3m/s to5m/s then change in momentum is

Answer 1

change in momentum =12 kg m/s

Answer 2

Given,
Mass (m) = 6kg
initial velocity (v1) = 3m/s
final velocity (v2) = 5m/s
We know that momentum of a body is product of mass and velocity.
So,
Initial Momentum= m×v1
= 6×3
=18kg.m/sec
Final Momentum= m×v2
= 6×5
=30kg.m/sec
Change in Momentum= Final Momentum - Initial Momentum
= 30-18
= 12kg.m/s
