A cart on an air track is moving at 0.5 m/s when the air is suddenly turned off. the cart comes to rest after traveling 1 m. the experiment is repeated, but now the cart is moving at 1 m/s when the air is turned off. how far does the cart travel before coming to rest?
The cart would travel 2 meters. If at first, the cart moving 0.5 m/s only traveled 1 meter when the air was shut off, we can assume that the doubling of the speed also doubles the distance traveled when the air is shut off again.
