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.(adsbygoogle = window.adsbygoogle || []).push({});

(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 got the answer for Part A right, but I can't seem to get the answer for part B. The answer i got for B is 940.8. I used the equation: W= -coefficient of kinetic friction*mg*distance but the answer is wrong. Am I using the wrong equation for Part B?
