Physics Question?

Hopping into your Porsche, you floor it and accelerate at 9.1 m/s^2 without spinning the tires. Determine the minimum coefficient of static friction between the tires and the road needed to make this possible.

Please show/explain all work clearly please.

Ignoring all sorts of things that would affect this answer in the real world:

The weight of the Porsche is mg, and the normal force N is also mg. The force of friction is uN. So...

F = uN = ma

You know everything else; solve for the coefficient of static friction u.
