Consider a damped pendulum consisting of a ball of mass M and radius a suspended by a fine wire of length L below a pivot. The ball is moving through a fluid of viscosity y, and this retards its motion. It is assumed that the ball moves sufficiently slowly that Stokes law applies. Under these conditions, the equation describing the motion of the sphere is given by ML =-Mg sin 0 - 6xual, The initial conditions are 012-= 0, and...
