A 2000 kg car negotiates a curve of radius 40.0m on a level road. The static friction coefficient between the tires and the pavement is 0.7. Calculate the maximum force of static friction for the car and the maximum speed with which it will be able to negotiate the curve.

The maximum static frioction force is the weight of the car (M g) multiplied by the static friction coefficient (0.7). Set that equal to the centripetal force (M V^2/R) to solve for the maximum speed. The car's mass M will cancel out
