AP Physics 1
2.9 Circular Motion
2.7 Kinetic and Static Friction
A car is negotiating an unbanked circular turn on dry road at its maximum safe speed of \(17\,\text{m/s}\). However, a long wet patch in the road appears and decreases the maximum static frictional force to one-fifth of its dry-road value. If the car is to continue safely around the curve, by what factor would it need to change the original velocity?
