Scott and Jafar are ready to work a problem. In this simulation, assume the coordinates of the points are as follows. A (0 s, 30 m); B (10 s, 50 m); C (20 s, 38 m); D (30 s, 0 m); E (40 s, −38 m); and F (50 s, −50 m) Recall the definitions of average speed, vavg ≡ d Δt , and average velocity in the x direction, vx ,avg ≡ Δx Δt . Find the average speed from circled A to circled F.
