Optimizing Energy Efficiency through Speed Ratio Analysis

Conserving Energy

The Attempt at a Solution

I started out using the above formula, but I don't understand how to get the speeds when only the masses are given.

When all is said and done, where is the center of mass of the system?

We haven't really discussed center of mass in detail in Momentum, but is it in between the two boats?

It is between the two boats, but that is not the point. It is initially at rest and you need to consider the question whether the center of mass will start moving or not when these guys start throwing balls around.

Why did you edit out the statement of the problem? How can I provide more help if I cannot see it?
