Halliday, Resnick & Walker — Kinetic Energy and Work: Problem 58

To pull a 50 kg crate across a horizontal frictionless floor, a worker applies a force of 210 N, directed 20° above the horizontal. As the crate moves 3.0 m, what work is done on the crate by (a) the worker’s force, (b) the gravitational force, and (c) the normal force? (d) What is the total work?

📝 Solution Approach

Given: 50 kg, , a, 210 N, 3.0 m

Find: (a) the worker’s force; (b) the gravitational force; (c) the normal force?
