Question

Momentum of a body moving in a straight line is p=(t^2+2t+1)kg m/s Force acting on a body at t=2 sec is​

Answer 1

Hey Dear,

◆ Answer -

F = 6 N

● Explaination -

Force acting on the body can be calculated as rate of change of momentum.

F = d(t^2+2t+1)/dt

F = 2t + 2

Force at t = 2 s,

F = 2×2 + 2

F = 6 N

Therefore, Force acting on the body at t = 2 s is 6 N.

Thanks dear...
