What are the magnitude of the car's acceleration at t= 10.0s ?

If the car has rubber tires and the track is concrete, at what time does the car begin to slide out of the circle?

For part A, i used F=ma=mv^2/r but that answer was wrong so im not sure which equation to use now.

and for part b

u(rollling)= 0.02 so u(rolling)*Fn= Ffriction but im not sure how to find the time
