Question
In the figure, a 200-kg crate is on a rough surface inclined at 30°. A constant external force P = 1600 N is applied horizontally to the crate. While this force pushes the crate a distance of 3.0 m up the incline, its velocity changes from 1 m/s to 2.4 m/s. How much work does friction do during this process?
