Question

Two cars travel on the parallel lanes of a two-lane road. The cars are at same location at time t = 0 s, and move in such a way as to produce the velocity (relative to the ground vs. time graph shown in the figure. (Intro 1 figure) On the graph, one vertical block is equivalent to one velocity unit. Rank car #1's speed relative to car #2 at the lettered times. Rank from largest to smallest. To rank items as equivalent, overlap them. Rank the distance between the cars at the lettered times. Rank from largest to smallest. To rank items as equivalent, overlap them.

Explanation / Answer

Masteringphysics says for part C "Although the two cars are moving at the same speed at time E, they are quite a large distance apart, since they were initially moving in opposite directions."
