Problem: An RC car skids across a kitchen floor and across an xy coordinate system from the origin to a point with xy coordinates (3.0 m, 4.0 m). During this slide the force of friction on the car is constant. The friction force has magnitude of 2.0 N and is directed at a counterclockwise angle of 100 from the positive direction of the x-axis. How much work is done by the friction force on the RC car during the displacement?
