4 2. The speed of a small jet aircraft was measured every 5 seconds, starting from the time it turned onto a runway, until the time when it left the ground. The results are given in the table below with the time in seconds and the speed in m sí . Time (s) 0 5 10 15 20 25 Speed (m sí ) 2 5 10 18 28 42 Using all of this information, (a) estimate the length of runway used by the jet to take off. (3) Given that the jet accelerated smoothly in these 25 seconds, (b) explain whether your answer to part (a) is an underestimate or an overestimate of the length of runway used by the jet to take off.
