    Acceleration around a running track

    If it is asking to find the acceleration then I assume I will be using a=rα to convert the angular acceleration from α=ω/t to 'linear' (not sure if that's that right word) acceleration. The problem is I can't find the time or if the displacement of 400m is relevant. And yes I think it is meant...

    Acceleration around a running track

    Homework Statement He is running around a running track training for a 400m race. His velocity is 5.11m/s around the circular end of the track, which has a radius of 31.8m. I'm trying to find his acceleration which I know is 0.821ms-2 but I can't find out how to get it. Homework Equations v=rω...
