I've been thinking more about it. The logger and the log is at rest, so the center of mass of the system is zero. Once the logger moves in one direction along the length of the log, he is moving at 1.2 m/s.
I understand that if you use conservation of momentum, that the log must move in the...
Homework Statement
Some friends and I were working on some physics questions and when it came to this one, we all got different answers.
An 90 kg logger is standing on a 400 kg log floating at rest in a pond. The logger starts to
walk along the log at 1.5 m/s relative to the water. How...
