a 1.9kg ball of putty moving to the right has a head -on inelastic with 1.3 kg putty ball moving to the left , if the combined blob doens;t move just after the collision, what can you conclude about the relative speeds of the balls before they collide?

  • physics -

    The relatave speeds of the balls are inversely prop to the mass ratios:

    ball going to right has 1.3/1.9 of the speed going to the left.

  • physics -

    1.9
