You are driving to the grocery store at 20 m/s . You are 110m from an intersection when the traffic light turns red. Assume that your reaction time is 0.50s and that your car brakes with constant acceleration.
_ How far are you from the intersection when you begin to apply the brakes?
_ What acceleration will bring you to rest right at the intersection
_ How long does it take you to stop after the light changes.?
