A 2.90 x 102 Newton force is pulling a 90 kilogram refrigerator across a horizontal surface. The force acts at an angle of 17.0Â degree above the surface. The coefficient of kinetic friction is 0.200, and the refrigerator moves a distance of 8 meter.
(a) Compute the work done by the pulling force.
______ J
(b) Evaluate the work done by the kinetic frictional force.
_______J
