Question

Suppose that motion studies of a runner show that the maximum speed she can maintain for a period of about 10 seconds is 12 m/s. If in a 100-meter dash this runner accelerates with a constant acceleration until she reaches this maximum speed and then maintains this speed for the rest of the race, what acceleration is required if her total time is 11 seconds?

Step 1

- Maximum speed (\(v_{\text{max}}\)) = 12 m/s - Total distance (\(d\)) = 100 meters - Total time (\(t_{\text{total}}\)) = 11 seconds - Acceleration (\(a\)) = ? - Time to reach maximum speed (\(t_1\)) - Distance covered during acceleration (\(d_1\)) - Distance Show more…
