Title: Forces
Post by: Studyinghard on March 28, 2011, 10:11:23 pm

A cyclist rides up a steady slope for 1200m, and rises 90m vertically as a result. The total mass of rider + cycle is 80kg.

a) assume a drag force of 10N opposing the motion, what total work must be output by the rider for this climb?

Do we use mgh and then Work = Fd
