A person jogs eight complete laps around a 400-mm track in a total time of 14.0 minmin . Part A Part complete Calculate the average speed, in m/sm/s. v¯v¯ = 3.81 m/sm/s SubmitPrevious Answers Answer Requested Part B Calculate the average velocity, in m/sm/s.
a runner travels 1.5 laps around a circular track in a time of 50 s . The diameter of the track is 40 m and its circumference is 126 m. Find (a) the average speed of the runner and (b) the magnitude of the runner’s average velocity. Be careful here ; average speed depends on the total distance traveled, whereas average velocity depends on the displacement at the end particular journey

Compute your average velocity in the following two cases: (a) You walk 73.2 m at a speed of 1.22 m/s and then run 73.2 m at a speed of 3.05 m/s along a straight track. (b) You walk for 1.00 min at a speed of 1.22 m/s and then run for 1.00 min at 3.05 m/s along a straight track, (c) Graph x versus t for both cases and indicate how the average velocity is found on the graph.
