A squirrel starts at building A at time t=0 and travels along a straight wire connected to
building B. For 0sIs18, the squirrel's velocity is modeled by the piecewise-linear function
defined by the graph above.
a) At what times in the interval 0<t<18, if any, does the squirrel change direction? Give a
reason for you answer.
b) At what time in the interval 0sis18 is the squirrel farthest from building A? How far from
building A is the squirrel at this time?
c) Find the total distance the squirrel travels during the time interval 0sts18.
d) Write expressions for the squirrel's acceleration at(), velocity ut), and distance x(t) from the
building A that are valid for the time interval 7 t<<10.
