Homework Help: Centripetal acceleration of a wheel

  1. Apr 5, 2007 #1
    1. The problem statement, all variables and given/known data
    A wheel of radius 1.0 m is rotating with a constant angular speed of 2.0 rad/s. What is the centripetal acceleration of a point on the wheel’s rim?
    A) 1.0 m/s2
    B) 4.0 m/s2
    C) 0.50 m/s2
    D) 2.0 m/s2

    2. Relevant equations
    Would it be v^2/r?

    3. The attempt at a solution
    If the equation is correct, it is 4.0 m/s^2

    Thanks!
