A car accelerate at 11 m/s2 without spinning the tires. Determine the minimum coefficient of static friction between the tires and the road needed to make this possible.

Answer 1

Net force is provided by the friction, which means

Fnet = Ff

ma = µ mg

µ = a/g = 11/9.8 = 1.1

Hence, coefficient of static friction is 1.1
