5. A 10kg mass is attached to a spring hanging from a ceiling. This causes the spring to stretch 2m on coming to rest at equilibrium. At time t = 0 an external force f (t) = 20cos4t is applied to the system. Let the damping constant B = 3, formulate a differential equation describing the system and use the method of undetermined coefficients to determine the steady state solution of the system and sketch one cycle of the sine wave form of the steady state.
