Chapter 4.6, Problem 5ES

Sketch a reasonable graph of $s$ versus $t$ for a mouse that is trapped in a narrow corridor (an $s\text{-axis}$ with the positive direction to the right) and scurries back and forth as follows. It runs right with a constant speed of $1.2\text{ m/s}$ for a while, then gradually slows down to $0.6\text{ m/s,}$ then quickly speeds up to $2.0\text{ m/s,}$ then gradually slows to a stop but immediately reverses direction and quickly speeds up to $1.2\text{ m/s}$ .
