A bicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.0 degrees with the horizontal. Calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 19.0 m up the hill. The combined mass of the rider and the bike is 88.0 kg. 1) Calculate the work done by gravity. 2) Calculate the work done by the person.
