Randall D. Knight — Work and Kinetic Energy: Problem 35
An 8.0 kg crate is pulled 5.0 m up a 30° incline by a rope angled 18° above the incline. The tension in the rope is 120 N, and the crate’s coefficient of kinetic friction on the incline is 0.25. a. How much work is done by tension, by gravity, and by the normal force? b. What is the increase in thermal energy of the crate and incline?
📝 Solution Approach
Given: 8.0 kg, 5.0 m, 120 N, 0.25. a
