1. The problem statement, all variables and given/known data (III) A cyclist intends to cycle up a 7.50° hill whose vertical height is 125 m. The pedals turn in a circle of diameter 36.0 cm. Assuming the mass of bicycle plus person is 75.0 kg, (a) calculate how much work must be done against gravity. 3. The attempt at a solution My question is about the wording about a. Work done against gravity is done by the cyclist right? So Shouldn't the computation of this be W = mgh + W(done by sliding force) and not just mgh? Can explain the wording of these type questions. The way it seems to me it's asking the work done by the cyclist.
