A 300N force is pulling an 90.0 kg refrigerator across a horizontal surface. The force acts at an angle of 22.0° 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({});

i found out the work done by pulling force is 1669 J and its asking for the work done by the kinetic frictional force!

here's what i did but the answer is wrong though...i tried a million times and it's still wrong! i know something's wrong here and i know it's not the acceleration of gravity or m...hmm

i did

mg times mu=9.8*90*.2

then i times it by the distance to get work. 176.4N*6m=1058.4 J

which is WRONG! arghh.......am i missing something here? :rofl:
