if you have a Newton's cradle consisting of, say, 5 balls, and you displace 2 of these to the left and let them go, we say they hit the others with velocity v. I was just wondering if the balls would have different velocities at the point of impact since they will have inevitably fallen from slightly different heights (i.e more GPE = more KE?) Does the back one speed up more and then just push the second one so they do have the same velocity? thanks.
