Acceleration
A sports car and a school bus are driving and the speed limit is 30 Mph, the school bus will drive a lower acceleration than the sports car because sports car usually have a greater acceleration they tend to speed up a lot. They both will possibly have a constant velocity because the school bus and the sports car distance and speed will stay the same. Once they see the red light the sports car and the school bus will have a negative acceleration since there will be slowing down. For the school bus it will be easier for it to slow down because it wasn't going as fast as the sports car.
They were both going the same speed! The sports car will actually slow down faster.
