The motion of an harmonic oscillator is governed by the differential equation 2¨x + 3 ˙x + 4x = g(t).

i. Suppose the oscillator is unforced and the motion is started from rest with an initial displacement of 5 positive units from the equilibrium position. Will the oscillator pass through the equilibrium position multiple times? Justify your answer.

ii. Now suppose the oscillator experiences a forcing function 2e t for the first two seconds, after which it is removed. Later, the oscillator is given a blow with a hammer that instantaneously imparts 3 units of force at precisely 5 seconds. Find g(t) in this case. No points awarded for answers written piecewise.
