Answer to Question #80947 in Physics for Aygo

Question

A position-time graph for a particle moving along the x axis is shown in the figure. The divisions along the horizontal axis represent 1.75 s and the divisions along the vertical axis represent 4.0 m.

(a) Find the average velocity in the time interval t = 5.25 s to t = 14.00 s.

(b) Determine the instantaneous velocity at t = 7.00 s (where the tangent line touches the curve) by measuring the slope of the tangent line shown in the graph.
