1. The problem statement, all variables and given/known data How fast (in rpm) must a centrifuge rotate if a particle 7.0 cm from the axis of rotation is to experience an acceleration of 1.2×10^5 g's? 3. The attempt at a solution well first i made 7 cm .07 m. then i changed acceleration to 1.18x10^6 m/s^2 by multiplying 1.2x10^5 g's by 9.8. at this point i no longer know what to do. i am having trouble relating linear velocity, centripetal velocity, and angular velocity now. rpm means centripetal velocity, which is equal to 2πr/T, and i believe its centripetal velocity that equals rω. and acceleration = v^2/r nd i dont know where to go from there.
