If the coefficient of static friction for tires on a road is 0.25, at what maximum speed can a car round a level 47.5 m radius curve without slipping?
The maximum speed possible, Vm, is that for which the centripetal force equals the maximum possible friction force
MVm^2/R = M*g*Us
where Us is the statc friction cefficient.
Vm = sqrt(g*R*Us)
