A 2 kg metal plate slides down a 11meter high slope. At the bottom its speed is 7.5 m/s. To the nearest Joule, what was the magnitude of the work done by friction?If the slope in the above problem is 22 degrees, what is the coefficient of friction?

bobpursley,
InitialPEfriction=final KE
solve for friction work.
Now, friction work= mu*mg*cosTheta*11meters
solve for mu.
