Question
A car goes around a flat curve of radius 50m at a speed of 35mph. What must be the minimum coefficient of static friction between the tires and the road for the car to make the turn?
r=50m
v=35mph=15.65m/s
F_sf=?
I know that F+sf= (meu)(F_N)
But the mass of the car isn't given how would I solve this problem?
Is F_sf=(mv^2)/r? But again were aren't given mass.

The centripetal force has to be supplied with the tires.
m*v^2/r= mg*mu
m*v^2/r= mg*mu
