1. The problem statement, all variables and given/known data I am asked to find the Hamilton equations for a block on an inclined plane (no friction) 2. Relevant equations 3. The attempt at a solution Please ignore the fact that my steps are written in French (sorry!) I am no longer sure of what i'm doing when it comes to finding the momentum. I here chose y' and just ignored the x', because that seemed logical to me at the time. How can I correct my solution if it isn't right?
