A 19.6 kilogram block is dragged over a rough, horizontal surface by a constant force of 75.7 Newton acting at an angle of 27.1o above the horizontal. The block is displaced 19.9 meter, and the coefficient of kinetic friction is 0.13. The acceleration of gravity is 9.8 m/s2.
Determine the work done by the75.7 N force.
Answer in units of J.
Determine the magnitude of the work done by force of friction.
