Problem: A 17.4kg block is dragged over a rough, horizontal surface by a constant force of 160N acting at an angle of 25.1 degrees above the horizontal. The block is displaced 23.1m, and the coefficient of kinetic friction is 0.229.
Part A: Find the magnitude of the work done by the force of friction.
Answer in units of J
I need help to find the magnitude of the work done by the force of friction.
