A body of mass 20kg is moving along straight line with a linear moment

1.	A body of mass 20kg is moving along straight line with a linear momentum of 240kgm/s.If a constant force of 20N acts for 5 seconds opposite to the direction of motion, the work done by the force during this time is?
Answer» 1200JExplanation:GIVEN:-Mass (m) = 20kgMomentum (P) = 240kgm/sForce (F) = 20NTime (t) = 5secWork (W) = ?We know,p=mv (where v is VELOCITY)v=p/m = 240/20 = 12m/salso,s = v×t (where s is displacement)s = 12×5 = 60mNow,W = F×sW = 20×60W = 1200J
