A block of mass 3.0 kg starts at a height 0.60 m on a plane that has an angle of 30 degrees from the horizontal. Upon reaching the bottom, the block slides along a horizontal surface. If the coefficient of friction on both surfaces is 0.20, how far does the block slide on the horizontal surface before coming to rest?(adsbygoogle = window.adsbygoogle || []).push({});

I found the net force on the block and from there the acceleration, but i think this problem is supposed to be solved using Conservation of Energy theory, or something along those lines.

I know E initial cannot = E final since friction is acting on the block, but i'm not sure how to work that into the problem.

Can anyone help with this question?
