The plot below displays the velocity as a function of time for two physics students, Alan and Betty, for 10 seconds after a stopwatch is started at time0. Alan and Betty are both initially standing at the same position, defined as x -0, and subsequently move along a straight line that we define as our x-axis. The plot for Betty's velocity as a function of time vs() is itself a straight line while the plot for Alan is a quadratic...
