Prior Knowledge Question (Do this BEFORE using the Gizmo.)A boy rolls an old car tire down a hill. It goes pretty fast, but he wants the tire to go even faster. So, the boy climbs inside and rolls down the hill inside the tire. Assuming there are no crashes, how do you think the speed of the tire with the boy inside will compare to the speed of the empty tire
