Cube subjected to an impulse

  1. Feb 25, 2009 #1
    I'd be grateful if someone could help me with the problem below:

    A free-floating uniform cube with sides of length 2 is at rest,
    aligned with the coordinate axes, when it is subjected to an
    impulse along one edge of 3m, where m is its mass. What
    is the effect on its motion? (Its inertia tensor is 2/3mI)

    Do I calculate the angular velocity or what? And how?

    Thanks for any help.

    Welcome to PF!

    Hi sabatier! Welcome to PF! :smile:

    (how can impulse have dimensions of mass? :confused:)

    You have to calculate the velocity of the centre of mass, and the angular velocity (including specfiying the axis of rotation) relative to the centre of mass. :wink:
