A standard man uses a bicycle of mass 30 kg to travel at constant speed along a 5 km long road up
a hill. The hill rises 250 m above the starting point and the man needs 30 minutes to get to the top.
How much work does the man do during the trip? What was the power use during the trip?

    Work=mgh==30•9.8•250 =...
    Power =mgh/t=30•9.8•250/30•60 =...
