Homework Help: Vectos angular momentum

  1. Nov 1, 2004 #1
    A particle is at the position (x,y,z) = (1.0, 2.0, 3.0) m. It is traveling with a vector velocity (-4.0, -5.6, -5.4) m/s. Its mass is 7.6 kg. What is its vector angular momentum about the origin?

    The angular momentum is [itex]\vec L = \vec r \times \vec p[/itex]
    It's pretty straightforward. You're given [itex]\vec r[/itex] and getting [itex]p[/itex] from [itex]m[/itex] and [itex]v[/itex] is easy.
    So just calculate their cross product.
