A car rounds a banked curve. The radius of curvature of theroad is R, the banking angle is ?, and the coefficient of staticfriction is µ.
(a) Determine the range of speeds the car can have without slipping up or down the road.
(b) Find the minimum value for µ, such that the minimumspeed is zero.
(c) What is the range of speeds possible if R = 100m, ?= 10.00degrees, µ=0.100 (slippery conditions)?
