You are driving to the grocery store at 26 m/s. You are 105 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.50 s and that your car brakes with constant acceleration.

(a) How far are you from the intersection when you begin to apply the brakes?

(b) What acceleration will bring you to rest right at the intersection?
