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

I'm not exactly sure what to do here I know the formulas are

uk = Fk/Fn

Us = Fs, max/Fn

not exactly sure how to do this problem with only this information
