A driving force of the form F(t)=(0.237 N) sin(2pi*f*t) acts on a weakly damped spring oscillator with mass 5.72 kg, spring constant 302 N/m, and damping constant 0.292 kg/s. What frequency of the driving force will maximize the response of the oscillator? Find the amplitude of the oscillator's steady-state motion when the driving force has this frequency.
