Conceptual: bug masses on a rotating wheel

  1. Feb 12, 2012 #1
    1. The problem statement, all variables and given/known data

    Two objects of equal mass are on a turning wheel. Mass 1 is located at the rim of the wheel while mass 2 is located halfway between the rim and the axis of rotation. The wheel is rotating with a non-zero angular acceleration. For each of the following statements select the correct option to complete the statement.

    Each of these statements have variables that are underlined

    1. For a given time, mass 2 travels a distance that is less than the distance traveled by mass
    2. The magnitude of the total acceleration of mass 1 is greater than the total acceleration of mass.
    3. For a given time, the angle covered by mass 2 is equal to the angle covered by mass 1.
    4. For a given time, the angle covered by mass 2 is equal to the angle covered by mass 1.
    5. The angular acceleration of mass 2 is equal to the angular acceleration of mass 1
    6. The centripetal (radial) acceleration of mass 2 is less than the centripetal acceleration of mass 1.
    7. The tangential acceleration of mass 2 is equal to the tangential acceleration of mass 1.

    2. Relevant equations

    ac=v2/r
    T=(2[itex]\pi[/itex])/ω


    3. The attempt at a solution

    I tried using the relevant equations to prove these statements but it didn't work. I'm not sure which statement is false, or if there's more than 1 wrong statement.
