Center Mass velocity

  1. Feb 20, 2007 #1
    1. Two 30 kg masses have velocities (in m/s) of v 1 = 14 i - 18 j and v 2 = - 28 i + 14 j. Determine the velocity of the center of mass of the system.

    I am having a problem on how to set the problem up to find the velocity in terms of v= i and j

    Start with conservation of momentum
