An object is moving down a ramp that has mu=0.150. It initially starts at (0,1), and the bottom of the ramp is at (sqrt(3),0) Show that the parametric down the ramp are given by:

I know the kinematics equations and have been covering ramps and such for a couple weeks now, but this came completely out of the blue, I don't even know which equations to use for derivatives (S = S1 + Vt + 1/2atÂ² was my best try, but I don't really know what to do.
