You are driving your car along a flat, curved road; the curve in the road is a segment of a circle with radius 50 meters. (We call this a "radius of curvature"). How fast can the car drive around the curve if the coefficient of static friction between the tires and the road is 1.0 (tires on dry pavement)? What if the coefficient of friction is 0.2 (tires on ice)?

A car of mass M = 1300 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is banked at an angle θ, and there is no friction between the road and the car's tires as shown in (Figure 1) . Use g = 9.80 m/s2 throughout this problem. r= 91.43 m. Now, suppose that the curve is level (θ=0) and that the ice has melted, so that there is a coefficient of static friction μ...
