A 280 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 6.00 m. (a) Find the work done by the pulling force. 1.60*10^3 J (b) Find the work done by the kinetic frictional force. J I have the answer for part a, but i keep getting the wrong answer for part b. Can someone please help me solve this problem?
