Homework Statement
An automobile traveling at 30.0 km/h has tires of 85.0 cm diameter.
(b) If the car is brought to a stop uniformly in 15.0 complete turns of the tires (without skidding), what is the magnitude of the angular acceleration of the wheels?
(In part a I found the angular speed to be 19.6 rad/s
Homework Equations
(w^2 - wi^2)/(2 * change in theta) ??
The Attempt at a Solution
-wi^2/(2 *(2* 15pi) = angular acceleration
I'm super lost and would appreciate any help at all. I just need a pointer in the right direction!
