3. An undamped spring-mass system has a mass that weighs 48 lb and a spring constant 0.5 lb/in. The mass is suddenly set in motion at t = 0 by an external force of 3 cos (2t) lb. Assume that the gravitational acceleration is 9 32 ft/s². Find the ODE which describes the position of mass as a function of time t. Solve it by the method of undetermined coeffi- cients. -
