Consider the classical mechanical description of a one-dimensional harmonic oscil lator of mass 0.2 kg , with spring constant k 5 n/m, (linear) damping constant b 0.2 ns/m. this oscillator is subject to a sinusoidal driving force of strength f 0.5 n and frequency f 0.5 hz (i irrespective of the initial conditions, after a long time the oscillator will ex- ecute regular sinusoidal oscillations. what will the frequency and amplitude of the oscillator's motion be? what is the phase of these oscillations relative to the driving force? (ii) write down newton's second law for the oscillator. identify all forces acting on the oscillator (assume gravity plays no role). indicate which of these forces are conservative and explain why. for each conservative force give the associated potential energy
