A 75 kg box slides down a 25o ramp with an acceleration of 3.6 m/s2. Find the coefficient of kinetic friction between the box and the ramp.

The component of gravity down the plane is mg*SinTheta
The normal component of mg*CosTheta
So
Net force=ma
gravitydownrampfriction=ma
mgSinThetamg*mu*CosTheta=ma
solve for mu.
