A spring is suspended vertically from a fixed support. The spring has spring constant k = 48 N m-. An object of mass m = to the bottom of the spring. The object is subject to damping with damping constant BN m- s. Let y(t) be the displacement in metres of the end of the kg is attached spring below its equilibrium position, at time t seconds. (d) Suppose that an external force of F(t) Newton directed downwards is applied to the spring. With B = 0, for which function(s) F from the list below would resonance occur? Select all that apply. A. e-' sin(v81) B. e sin(6/81) C. 2 cos(-6v81) D. sin(6/81) E. cos(v8t) F. 2 sin(v8t) G. 5 cos(v8t) + e-
