A particle of mass 100kg is experiancing a constant force of 100N get accelerated from rest to the velocity of 10m/s caculate the work done by force.
Assume that the force is acting always in the direction of desplacement vector.
The answer is 5000.

Here,m=100 kg,F=100 N,so a=F/m=100/100=1 m/s^2,Now we know that v^2=u^2+2aS or (10)^2=0^2+2 * 1 * S or 100=2S or 100/2=S so S=50 m, then W=Fs=100 * 50=5000 J
