URGENT: Finding Mechanical Energy, Velocity, and Height 1. The problem statement, all variables and given/known data http://www.mrfizix.com/home/energy_files/image051.gif 2. Relevant equations E0=EF PE=mgh KE=(1/2)mv2 3. The attempt at a solution I understand how to get the potential and kinetic energy values but I'm confused as to how to get the mechanical energy, velocity, and height values. Any help would be appreciated!
