Question:

Figure 2.34 shows the velocity of a solar-powered car as a function of time. The driver accelerates from a stop sign, cruises for 20 s at a constant speed of 60 km/h, and then brakes to come to a stop 40 s after leaving the stop sign.
(a) Compute the average acceleration during the following time intervals: (i) t = 0 to t = 10 s; (ii) t = 30 s to, = 40 s; (iii) t = 10 s to t= 30 s; (iv) t = 0 to t = 40 s.
(b) What is the instantaneous acceleration at t = 20 s and at t= 35s?
