**Blanca**, Saturday, January 21, 2012 at 1:09pmI need to answer: What is the centripetal acceleration of the ball at 7.80 rev/s? and What is the centripetal acceleration at 6.51 rev/s?

**drwls**, Saturday, January 21, 2012 at 3:39pmMultiply the rev/s numbers by 2 pi to get radians per second, and call that w.

The centripetal accleration is R*w^2 in both cases. However, different R and w values apply in the two cases.

The centripetal acceleration value will be close for the two cases, but not quite the same.
