Acar (m = 2000 kg) is going around an unbanked curve at the recommended speed of 11m/s (24.6 mph). (a) if the radius of the curvature of the path is 25m and the coefficient of static friction between the rubber tires and the road is µs = 0.70, does the car skid as it goes around the curve? (b) what will happen if the driver ignores the highway speed limit sign and travels at 18 m/s (40.3 mph)? (c) what speed is safe for traveling around the curve if the road surface is wet from a recent rainstorm and the coefficient of static friction between the wet roud and the rubber tires is µs = 0.50?
