A curve of radius 65m is banked for a design speed of 105 km/h. If the coefficient of static friction is 0.34 (wet pavement), at what range of speeds can a car safely make the curve?

I am not sure how can I get range of velocities at which the car can travel without skidding

2. Relevant equations

F = mA

F = ukFN

A = (v^2) / R

3. The attempt at a solution

uk x FN = mA

uk x mg =m(v^2)/r

v = sqrt [uk x r x g]

v = sqrt[ 0.34 x 65 x 9.8] = 14.72 m/s -> 53 km/hr
