A 1300 kg car rounds a curve of radius 70 m banked at an angle of 12°. If the car is traveling at 88 km/h, how much friction force is required?
ok so this is what i did so far but i got stuck.
the sum of Fy = mg - Fncos(angle) + Ffrsin(angle) = ma = 0
the sum of Fx = Fnsin(angle) + Ffrcos(angle) = ma = mv^2/r
i don't know how to get Ffr alone from here...help please!
