**drwls**, Tuesday, October 19, 2010 at 3:21amFirst write Newton's equation of motion for the direction down the ramp.

Fnet = Weight*sin 36 - Ffriction = M a

M g sin36 - M g cos36 *Uk = M a

Cancel the M's and solve for the kinetic friction coefficient Uk.

For further help from me, show your work.
