Back(II) A sports car accelerates approximately as shown in the velocity–time graph of Fig. 2–43. (The short flat spots in the curve represent manual shifting of the gears.) Estimate the car's average acceleration in second gear.
Given v(t) = 25 + 18t, where v is in m/s and t is in s, use calculus to determine the total displacement from t1 = 1.3 s to t2 = 3.6 s.
Figure 2–42 shows the velocity of a train as a function of time. During what periods, if any, was the velocity constant?

(II) Figure 2–42 shows the velocity of a train as a function of time. When was the magnitude of the acceleration greatest?
