(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What angular speed (in revolutions per

minute) is needed for a centrifuge to produce

an acceleration of 675 times the gravitational

acceleration 9.8 m/s^{2}at a radius of 15.4 cm?

Answer in units of rev/min.

2. Relevant equations

a_{c}=4 pi^{2}r f^{2}

3. The attempt at a solution

ok so first I found the acceleration which is 110.25 m/m^{2}and I converted the radius to meters r= .154 m then I solved for the frequency = ((110.25)/(4pi^{2}.154))^{1/2}= 1979.137 rpm

and my answer was wrong. Can you please tell me what error I made. thank you
