    The motion of spring when the length of string shortened

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Consider a simple plane pendulum consisting of a mass m connected to a string of length L.

    After the pendulum is set in motion , the length of the string is shortened at a constant rate:

    dL/dt = -k

    The suspension point remains fixed.

    Compute the following:

    a) The Lagrangian and Hamiltonian functions

    b) Compare the Hamiltonian and the total energy

    c) Discuss the conservation of energy for the system.

    Please give a through analysis
