A 1900 kg car starts from rest and drives around a flat 40.0 m diameter circular track. The forward force provided by the car's drive wheels is a constant 1000N .
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 I am not sure which equation to use now.
and for part b
u(rollling)= 0.02 so u(rolling)*Fn= Ffriction but I am not sure how to find the time
