Uniform Circular Motion Problem

[aki_23]

Homework Statement

1. A car is safely negotiating an unbanked circular turn at 21 m/s and the maximum static force acts on the tires. Suddenly a wet patch on the road reduces the static frictional force by a factor of three. At what speed must the driver slow to in order to safely continue on their journey?

Homework Equations

a=v2/r
