Figure E2.12 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 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:
