38. A box slides down a 30.0 degree ramp with an acceleration of 1.20 m/s^2. Determine the coefficient of kinetic friction between the box and the ramp.

I have no idea how to do this with only knowing the aceleration and the angle. Please tell me how to do this.

    The equation...

    Netforcedown ramp= mass*acceleration applies


    Netforce= weightdownramp-friction
    = mgSinTheta- mu*mg*CosTheta

    solve for mu. You need to be certain you can figure how both those terms were derived.
