1. A constant force of 12N acts on a body for 4s. Find the change in the linear momentum
of the body
1) 12 N-s
2) 24 N-s
3) 48 N-s
4) 28 N-s
12. Two balls A and B of masses m and 2m are in motion with velocities 2v and v respectivel
2a ball of mass 1kg is accelerates at the rate of 1m/s square the rate of change of momentum???​

Answer 1

Hey

Impulsive force = dp/dt = pf - pi /dt

Pf - pi = F(impulsive) * dt = 12 *4 = 48 N-s
