Homework Help: 2 discs, frictionless help!

  1. Oct 5, 2004 #1
    This is the question that i have on my paper...

    Two discs (both circular shape) on a frictionless table, disc 1 with mass 100g moves with velocity 1m/s and collides "head on" elastically without any energy loss with disc 2 with mass 200g and motionless; what will be the final velocity after collision?

    Thanks in advance!

    Use "conservation of momentum" and "conservation of energy". What have YOU done on htis?
