## 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.

What was the sprinter's average angular acceleration after 12.96 s? Answer in deg/s2. I.e., what was his average acceleration while running the curve?

## Homework Equations

This is for a biomechanics class. It's just a practice question to study but I am not in a physics program and this is my only math related course and i literally know very little about this. I have tried all of the formulas I know and I still can't get the right answer. Please help lol.
