Homework Help: Centripetal acceleration question confirmation please

  1. Dec 10, 2009 #1
    1. The problem statement, all variables and given/known data

    what is the magnitude and direction of the centripetal acceleration necessary to confine the motion of a 0.5kg mass moving at speed 0.1m/s to a circular path 0.2m in radius

    2. Relevant equations

    a = v^2/r

    3. The attempt at a solution

    0.1^2/0.2 = a

    a = 0.05m/s/s towards the centre

    Doesn't look right to me

    Thanks in advance
