Can someone verify my calculations here? I have a 5kg block on an incline plane 12 degrees down angle. Mu k is .31 and slides a distance of 1.5m down the ramp.(adsbygoogle = window.adsbygoogle || []).push({});

Work gravity=5k(9.8 m/s^2)sin(348)(1.5m)=-15.29J

Work friction=.31(5k(9.8 m/s^2)cos(348)(1.5m)=22.29J

This can't be right, can it?
