A cart is initially moving at 0.5 m/s along a track. The cart comes to rest after traveling I m. The experiment is repeated on the same track, but now the cart is initially moving at I m/s. How far does the cart travel before coming to rest?

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
