**Scott**, Wednesday, September 26, 2012 at 8:13pmit takes 5 s to stop the car __ 55 / 11

the average speed (Va) is __ (55 + 0) / 2

the stopping distance is __ Va * 5

twice as fast means that the stopping time is doubled, along with the average speed

__ this means that the car travels 4 times as far
