Problem 2-99 - v-t graph - (b)

Two cars, \(A\) and \(B\), are stopped for a red light beside each other at an intersection. The light turns green and the cars accelerate. Their velocity time graphs are shown in the figure below. (The positive direction is "forward.")

graph indicating car A and car B accelerating

(a) At what time(s) do \(A\) and \(B\) have the same velocity?
(b) When does \(B\) overtake \(A\)? (Hint: Their displacements must be equal at that time and displacement can be found from a velocity time graph.)
(c) How far have the cars traveled when \(B\) overtakes \(A\)?

No. Think about the question. Its almost at the level of "Who wrote Beethoven's 5th symphony?"
