You are driving to the grocery store at 12.2 m/s. You are 193.0 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.790 s and that your car brakes with constant acceleration. How far are you from the intersection when you begin to apply the brakes?

I got a correct answer of 1.83e+02 m

But this is what I am stuck on (part b)

What acceleration will bring you to rest as you just reach the intersection?
