Homework Help: Centripetal acceleration

  1. Apr 18, 2008 #1
    1. The problem statement, all variables and given/known data
    Calculate the magnitude of the centripetal acceleration at 8.4 cm from the centre of the centrifuge when it is spinning at 6.0x10^4 rpm. Express your answer in terms of g (acceleration due to Earth's gravity.)

    2. Relevant equations
    Ac = v^2 /

    3. The attempt at a solution
    I know the solution i just dont understand what they are asking from me when they say:
    Express your answer in terms of g (acceleration due to Earth's gravity

    g is 9.8m/sec^2. If you got an answer for the centrifuge question in m/sec^2 then just divide it by 9.8m/sec^2 to get the answer as a multiple of g.
