1.40 · 105 g?

The answer is supposed to be 517 1/s. How do I arrive at this answer. Thank you very much in advance.

**Damon**, Friday, June 15, 2012 at 8:59pmAc = v^2/r = w^2 r

where w = omega, angular speed = 2 pi f

1.4 *10^5 * 9.8 = w^2 (.13)

w^2 = 106 * 10^5 = 10.6 * 10^6

so

w = 3.25 * 10^3 = 3250 radians/s

f = w/2 pi = 517 sure enough
