Homework Statement
A 1000kg car travels around a frictionless banked curve having a radius of 80m. If the banking is 20 degrees to the horizontal, at which specific speed must the car travel to maintain a constant radius?
Homework Equations
Fc = mv^2/r
Fg(perp.) = mgcos(20)
The Attempt at a Solution
Would someone explain to me why we use the perp instead of the parallel angle on the incline? Is it because the car is traveling in the straight (toward the plane) direction along the banked curve?
