A 2 kg metal plate slides down a 11-meter 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?
solve for friction work.
Now, friction work= mu*mg*cosTheta*11meters
solve for mu.
