Question

A car of mass M r in Part A. Km/hour and that the radius of the curve is given by the value you found for r Mu min, the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 45.0km/hour Mu between the road and the car's tires.(Figure 2) What is ? min theta = 0) and that the ice has melted, so that there is a coefficient of static friction ? degree(assuming the car continues in uniform circular motion around the turn)? Now, suppose that the curve is level (?=0 theta= 20.0 ? rof the turn if ? m/s^2 throughout this problem. What is the radius r g = 9.80m/s 2 theta, and there is no friction between the road and the car's tires. (Figure 1) . Use g km/hour enters a banked turn covered with ice. The road is banked at an angle ? kg traveling at 45.0km/hour M = 1500kg

Explanation / Answer

apply banking angle tan theta = V^2/rg

so here r = V^2/( g tan 20)

also 1 Kmph = 5/18 m/s

so r = (45*5/18)^2/(9.8 * tan 20)

r = 43.8 m
