Motion Graphs | Velocity-Time Graph and Displacement-Time Graph

SOLVED:(a) Explain how you can use the graph of position versus time in Figure to describe the change in velocity over time. Identify (b) the time (ta, tb, tc, td., or .te) at which the instantaneous velocity is greatest, (c) the time at which it is zero, and (d) the time at which it is negative.

SOLVED: Position versus time graph of a particle is given in the figure. Plot roughly v-t and a-t graphs for this particle.
