In this assignment you want to work out the equations of motion of some simple mechanical system, the write a python program (or a Jypiter notebook) to animate the motion of the system, with given initial conditions. Send me the notebook or python files, plus a movie or two. Some suggested systems are A spherical pendulum A double pendulum (in the plane) A cart that can move along the x-axis that has a pendulum hanging down from it, and its attached to a wall on the left by a spring (remember Hooke's law). Make the cart and the pendulum more complicated A double spherical pendulum
