My Math and Physics knowledge has eroded from over 30 years of non-use though I can still integrate e^x with the best of you!!(adsbygoogle = window.adsbygoogle || []).push({});

My son wants to know how to determine the time it takes to travel/complete a circular arc in terms of the time it takes to travel the same distance going in a straight line ... assuming in both cases that the "linear velocity" is the same and is constant.

I may be expressing it incorrectly but I think he is trying to determine the additional time it would take a runner to travel the same distance on a circular track ... relative to the time it would take the same runner to travel that distance on a straight track ... both with identical surfaces.

Thanks!
