Problem
An automobile must negotiate a frictionless banked exit ramp that has a constant radius of curvature of 85m. Highway signs indicate that the ramp is ideally designed for a speed of 12∘ bank angle.
Assume g=9.8m⋅s−2.
(a) Calculate the speed a car must maintain in order to travel through the ramp without any assistance from tire friction.
(b) If a car maintained that speed while traveling all the way around a hypothetical full circle of radius 85m, determine the time required to complete one full revolution.
