Homework Statement
A car is traveling at 30m/s around a bend of radius 70m. What coefficient of static friction between the tires and the road is required to ensure the car will not slip?
Homework Equations
The Attempt at a Solution
I know that the centripetal acceleration is a=30^2/70
and I know that this acceleration has to be canceled out by the frictional force for the car to not slip, but I am not sure out to calculate frictional force F=mA without a mass for the car.
