A car is 200. m from a stop sign and traveling toward the sign at 40.0 m/s. If the driver realizes they must stop the car at this time. It takes 0.200 s for the driver to apply the brakes. What must the constant acceleration of the car be after the brakes are applied so that the car would come to rest at the stop sign?
