Please include thoroughly, and draw diagrams with the components. I am completely lost.

A bicyclist maintains a constant speed of 4.00 m/s up a hill that is inclined at 10.00 with the horizontal. Calculate the work done by the person and the work done by gravity if the bicycle moves a distance of 20.0 m up the hill. The combined mass of the rider and the bike is 90.0 kg. 1) Calculate the work done by gravity. (Express your answer to three significant figures.) - kJ 2) Calculate the work done by the person. (Express your answer to three significant figures.) kJ
