N A spring-mass system has a spring constant of 3. A mass of 2 kg m is attached to the spring, and the motion takes place in a viscous fluid that offers a resistance numerically equal to the magnitude of the instantaneous velocity. If the system is driven by an external force of 15 cos(3t) — 10 sin(3t) N, determine the steady-state response in the form R cos(wt - 8). - R = 532 w = 3 8 -T¹ X X
