A 3.00*10^2 N force is pulling an 80.0 kg refrigerator across a horizontal surface. The force acts at an angle of 18.0° above the surface. The coefficient of kinetic friction is 0.200, and the refrigerator moves a distance of 8.00 m.
(a) Find the work done by the pulling force.
(b) Find the work done by the kinetic frictional force.
