Part D
The figure (Figure 1) shows the velocity of a solar-
powered motorhome (RV) 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.
Compute the average acceleration during the time interval t =0 to t = 40s.
