4. A squirrel starts at building A at time 1 = 0 and travels along a straight, horizontal wire connected to
building B. For 0 sIS 18, the squirrel's velocity is modeled by the piecewise-linear function defined
by the graph above.
(a) At what times in the interval 0 < 1 < 18, if any, does the squirrel change direction? Give a reason
for your answer.
(b) At what time in the interval 0 < 1 s 18 is the squirrel farthest from building A ? How far from
building A is the squirrel at that time?
(c) Find the total distance the squirrel travels during the time interval 0 < 1 s 18.
