Question

is a continuation of problem 5.49.) 5) The Green's function for a linear oscillator that starts from rest is e-pe-e') sin((t- t)), for t2t G(t, t') =ma, 0, for t<t The solution for a forced oscillator with a forcing function F(t) is then x(t) F(t')G(t,&')d¢ 00 a) (3 pts) Calculate x(t) for an oscillator for the case where it is undamped, has natural frequency oo, and is driven by the following force function: it is zero before t 0, is constant with value Fo for 0<t<t, where t= 2r/0, and is zero again for t> t. b) (3 pts) Make a plot or sketch of the resulting motion of the oscillator c) (3 pts) Give an intuitive physical explanation for why the oscillator behaves the way it does for time t > t.
