Question

How large must the coefficient of static friction be between the tires and road, if a car rounds a level curve of radius 85 m at a speed of 23.5 m/s?

Answer 1

0.66

Step-by-step explanation:

By using the formula

u = v^2 / r g

Where u is coefficent of friction

u = 23.5 × 23.5 / (85 × 9.8)

u = 0.66
