Question

a block of masses 10kg is at rest on a table the body has a aquired a velocity of 10 M per second due to an external force after travelling certain distance the work done by the forces

Answer 1

Acc. to work energy theorem, Work done= Kinetic energy

So, W=K.E=1/2mv^2=1/2x10x10^2=5x10x10=500J
