Netforce(X/Y) = MA

Its going towards the center

Fnx is center pointing The mass is not given Apparently the masses should cancel out with teh formulas but I don't really know which ones to choose

Ok I drew out the FBD Fg going down Fny going up Fnx going to the right Fn going at a 68 degree angle to the horizontal Using the trig functions, I got: (not to significant figures) Fg = 9.8 [N] Fn = 9.8 [N] Fnx = 3.96 [N] Fn = 10.57 [N] Ac = (Vc^2)/(r) Fc = MAc = (MVc^2)/(r)

A curve of radius 170 m is banked at an angle of 22°. At what speed can it be negotiated under icy conditions where friction is negligible? Can someone explain how to get the answer for this question? Thanks
