## Homework Statement

(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.

## 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.
