[QUOTE="Dale, post: 5483341, member: 43978"] When you come up on these sorts of conundrums from "hand waving" arguments then the first thing you should do is actually work the math. Most of the time working the math will show you exactly where your thinking was going bad. Here, you would find the energy transferred into each object as a function of the energy in the spring, the two masses, and the initial velocity. [/QUOTE]
