Topic: Physics - Potential EnergyPerson A lifts a rock with a weight of 1.0 N through a height of1.0 m, and then lowers it back down to the starting point. Person Bpushes a table 1.0 m across the floor at constant speed, requiringa force of 1.0 N, and then pushes it back to where it started.
(a) Compare the total work done by person A and person B.Explain why.
(b) Check that your answers to part (a) make sense, using thedefinition of work: work is the transfer of energy. In your answer,you’ll need to discuss what specific type of energy is involved ineach case.
