A position-time graph for a particle moving along the x axis is shown in the figure. The divisions along the horizontal axis represent 0.75 s and the divisions along the vertical axis represent 3.0 m. Find the average velocity in the time interval t = 2.25 s to t = 6.00 s. Determine the instantaneous velocity at t = 3.00 s (where the tangent line touches the curve) by measuring the slope of the tangent line shown in the graph. At what value of t is the velocity zero?
Unfortunately, there is no diagram. V = S/t = 3/0.75 = 4 m/sec
