Question

The weight is twice as much as the external force applied to a body that weighs 40kg.​

Answer 1

Answer:

Given,

Mass=40kg,v=1m/s,v=2m/s

According to the work-energy conversion theorem;

Work done by the force= Change in Kinetic energy,

Work done by the force =( 21 )×m×(v

2 −u 2 )

Work done =0.5×40×(4−1)=60J
