A certain banked circular race track with angle of inclination Bis designed for cars traveling at a speci?c speed 00 to negotiate the curve without any help from theforce of friction from the road. Take 120: 50 km / h and 6 = 18°. (a) Find the radius R of the circular track. (b) If y, = 0.95 and ,uk = 0.70 between the ?res and the track, what are the maximumand minimum allowed speeds of the car such that it will not slide on the track?
