The velocity-versus-time graphs in Figure P4.17 all depict the motion of carts that have the same size and shape. The different graphs show motion on different tracks: a smooth icy track, a dusty unpolished track, and a rough damaged track. In one case metal carts are used, in one case plastic cars are used, and in one case one cart of each material is used. The carts may initially be moving in opposite directions, in the same direction, or one may be at rest. For each graph, label the track type, cart type, and initial motion. If you cannot determine a property, state why.
