1. The problem statement, all variables and given/known data A centrifuge rotates at 12000rpm, what is the radians per second? If the radius of the centrifuge is 150mm, what is the centripetal acceleration? 2. Relevant equations Angular Velocity: ω = Δθ/Δt (maybe, not sure) Centripetal Acceleration: a = v2 / r 3. The attempt at a solution To get the radians per second, I did 12000 x 2π = 24000π rads/min. Then to get this in rads/sec I just did 24000π / 60 = 400π rads/sec This gives me the tangential velocity (I think). Then for to get the centripetal acceleration, I firstly converted the 400π rads/sec to metres/sec: 400π x 0.150 = 60π = 188.5 m/s. I then used the formula for Centripetal Acceleration to get: a = 188.52 / 0.150 Which gave me: a = 236881.6 m/s2 Any and all help is welcome! If I've done this completely wrong please feel free to destroy everything I thought true and correct me like a Physics martyr.
