A 30 kg person climbs up a 5 m rope at a constant speed. If the student’s power output is 2 kW, how long does it take for the student to climb the rope? How much work does the student do?

The work done is obviously W = M g H, the potential energy increase.

For the time T, solve
W/T = Power = 2000 W
