Homework Statement


A curve of radius 16 m is banked so that a 940 kg car traveling at 44.4 km/h can round it even if the road is so icy that the coefficient of static friction is approximately zero. You are commissioned to tell the local police the range of speeds at which a car can travel around this curve without skidding. Neglect the effects of air drag and rolling friction. If the coefficient of static friction between the road and the tires is 0.300, what is the range of speeds you tell them?


Homework Equations

If the car were going too fast, it would slide up the banked turn. If the car were going too slow, its weight would make it slide down the slope of the banked turn.
