Question

According to the Work Kinetic Energy Theorem .......

A.work done on an object equals the kinetic energy gain or loss by the object

B.Wnet = ΔKE

C.A farmer heaves a 7.56 kg bale of hay with a final velocity of 4.75 m/s does 85.3 Joules of work

D.All of these are true

Answer 1

D. All of these are true. The kinetic energy of the hay is 1/2 m v² which is indeed 85.3 J.
