v = dx/dt
Slope of Position and time grapgh gives velocity
at 2 s and at 9s , slope is positive and it have greatet value.
so at 2 s and 8 s bus have greatest velocity.
at t= 3 s and at t = 6 s slope is zero so velocity is zero
at t= 5 s slope is negative , so velocity is negative

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...
