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 velocity from circled a to circled b. vx, avg = 11 2 correct: your answer is correct. m/s find the average velocity from circled b to circled d. vx, avg = 12 -2.5 correct: your answer is correct. m/s find the average velocity from circled a to circled f. vx, avg = 13 -1.6 correct: your answer is correct. m/s find the average speed from circled a to circled f. vavg = 14 1.6 incorrect: your answer is incorrect.
