Problem
The position–time graph of a motorbike is a smooth curve that becomes progressively steeper as time increases. Two points on the graph are marked: point P at t = 1.0 s and point Q at t = 3.0 s. Which of the following comparisons of the bike’s instantaneous velocity at the two points is most accurate?
(a) vP=vQ
(b) vP<vQ
(c) The comparison cannot be determined from the graph
(d) vP>vQ
