### Damped Harmonic Oscillator Driven by an External Force

A driving force of the form:

\[ F(t) = (0.281 \, \text{N}) \sin (2\pi f t) \]

acts on a weakly damped spring oscillator with a mass of 5.64 kg, a spring constant of 361 N/m, and a damping constant of 0.155 kg/s.

#### Question 1

What frequency \( f_0 \) of the driving force will maximize the response of the oscillator?

\[ f_0 = \_\_\_\_\_\_\_\_\_\_ \, \text{Hz} \]

#### Question 2

Find the amplitude \( A_0 \) of the oscillator's steady-state motion when the driving force has this frequency.

\[ A_0 = \_\_\_\_\_\_\_\_\_\_ \, \text{m} \]
