Question

Suppose the coefficient of static friction between the road and the tires on a Formula One car is 0.7 during a Grand Prix auto race. What speed will put the car on the verge of sliding as it rounds a level curve of 39.0 m radius?

Answer 1

Solve this equation for V:

M V^2/R = 0.7 M g

M (the mass) cancels out, so

V = sqrt(0.7 g*R)
