Suppose that you have a simple harmonic oscillator in 1-d, that you have decided tocall the coordinate for the mass,x(t), and that the Lagrangian for the system is then:L(x, x') =m x'^2/2-kx^2/2. (x' means x dot)
Determine the generalized momentum and se this generalized momentum and derive the Hamiltonian for the system. Do not just write it down. Derive it. Be sure to write your final result to emphasize theindependent variables for this Hamiltonian.
Determine the terminal voltage of each battery in the figure. Determine the terminal voltage of top battery. Express your answer to two significant figures and include the appropriate units.
