Consider a damped oscillator with m=0.2 kg, b= 4 N-m^-1 sec and k= 80N/m. Suppose that this oscillator is driven by a force F=Fo cos wt, where Fo =2N and w=30 sec^-1.

(a). What are the values A and delta of the steady-state response descrivbed by x=Acos(wt-delta)?

(b). How much energy is dissipated against the resistive force in one cycle?

(c). What is the mean power input?
