1. The problem statement, all variables and given/known data derive the equation of motion of a mass-spring-pulley system using lagrange's equations. A mass m is connected to a spring of stiffness k, through a string wrapped around a rigid pulley of radius R and mass moment of inertia, I. 2. Relevant equations kinetic energey T = 1/2 (m)(x_dot) + 1/2 (I)(theta_dot) potential energy V = 1/2 k(R)(x) 3. The attempt at a solution sorry for the sideways picture... dont know why its doing that. but please help homework is due tomorrow morning! thanks!
