An athlete starts at point A and runs at a constant speed of 5.40 m/s around a round track 250 . in diameter.

Find the x component of this runner's average velocity between points A and B.
GOT THIS!!! 3.4 m/s

Find the y component of this runner's average velocity between points A and B.
GOT THIS!!! 3.4 m/s

Find the x component of this runner's average ACCELERATION between points A and B.
nope. thought it was 0.95 because of a formula i found, but it is not.

Find the y component of this runner's average ACCELERATION between points A and B.
nope. thought it was 0.95 because of a formula i found, but it is not.


The change in velocity/time = average acceleration. I'm not sure how far apart the points are, so you'll need to figure that out.
