A 294 N force is pulling an 82.6-kg refrigerator across a horizontal surface. The force acts at an angle of 24.4 ° above the surface. The coefficient of kinetic friction is 0.220, and the refrigerator moves a distance of 6.66 m. Find
(a) the work done by the pulling force, and
(b) the work done by the kinetic frictional force.
