A box slides down a 36° ramp with an acceleration of 1.05 m/s2. Determine the coefficient of kinetic friction between the box and the ramp.

• Physics -

First 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.
