When Maggie applies the brakes of her spinning car, the car slows uniformly from 15.0 rad/s to 0.0 rad/s in 2.50 s. How many radians will the car have traveled before coming to rest?
This is a question from an angular motion physics problem.

Explanation:
Angular acceleration of car is
#α = (ω_f - ω_i) / t = "0.0 rad/s - 15.0 rad/s"/"2.50 s" = -"6 rad/s"^2#
Now, angular displacement is given as
#θ = (ω_f^2 - ω_i^2) / (2alpha)#
