**Brittany**, Friday, February 24, 2012 at 12:13am90 degrees of a circle is 1/4 the Circumference. Therefore it takes 0.49s to travel 1/4 of the way. Multiply .49 by 4 to receive the total amount of time it takes to make one revolution. To find velocity, find the circumference (2*r*pi). Divide the circumference by the time to get the velocity. The Centripetal Acceleration is (v^2/r).
