The free oscillations of a mechanical system are observed to have a certain angular frequency ?₁. The same system, when driven by a force F₀cos?t, has a power resonance curve whose angular frequency width, at half-maximum power, is ?₁/5.

(a) At what angular frequency does the maximum power input occur?

(b) What is the Q of the system?

(c) The system consists of a mass m on a spring of spring constant k. In terms of m and k, what is the value of the constant b in the resistive term -bv?
