How large must the coeffficient of static friction be between the tires and the road if a car is to round a level curve of radius 120 m at a speed of 120 km/h express your answer using two significant figures.

Coefficient of static friction required = 0.94

Explanation:

Coefficient of static friction required

Velocity, v = 120 km/h = 33.33 m/s

g = 9.81 m/s²

R = 120 m

Coefficient of static friction required

Coefficient of static friction required = 0.94
