Homework Help: Angular impulse problem

  1. May 15, 2010 #1
    1. The problem statement, all variables and given/known data

    (Refer to attachment)

    2. Relevant equations

    None.

    3. The attempt at a solution

    5.1 Inelastic collision because they stick together.

    5.2 Impulse = Lf - Li
    = Iwf - Iwi
    = (1/2MR^2 + mR^2)w1 - (1/2MR^2)w0 + mRv0

    I tried to use this equation which is related to the linear one, but not sure if it is right for angular impulse. Also I dont understand whether you can have an impulse for 2 objects at the same time (as for example the linear equation F(t) = m(vf - vi), only has the mass of 1 of the objects, not both of them).
