    Angular Acceleration of a sprinter

    Sorry, the question is asking about his acceleration during the curve. Like throughout the whole 12.96 seconds. The previous question asked what the average velocity of the curve was so i took the time, displacement (180 degrees) and radius and found it was 13.88 degrees/s (which was the right...

    Angular Acceleration of a sprinter

    My notes say that Average Acceleration = the change in angular velocity divided by time? So would the change in angular velocity be 13.88 deg/s because that's what the velocity is at the end of the curve and he would have started at zero?

    Angular Acceleration of a sprinter

    Sorry, I know it is not a very well worded question. I haven't changed anything and that is word-for-word what the question is. I'm pretty sure it is asking the average angular acceleration for the whole curve. I've managed to find the average velocity which is 13.88 degrees, but I can't find...

    Angular Acceleration of a sprinter

    Homework Statement A sprinter runs the curve of this 200 m in 12.96 s. Assume he ran in a lane which makes a semicircle (r = 36.8 m) for the first part of the race. At 3.36 s into the race his speed is 5.1 m/s. At 7.6 s into the race his speed is 9.6 m/s. His speed after the curve was 11.1 m/s...
