Consider a damped oscillator with m = 0.2 kg, k = 100 N/m, and b = 5 N-s/m. The oscillator is driven by a force F= (1.6 N) cos 20r. (a) If the displacement is given by x = A cos(wt - 8), what are the values of A and 8? (b) Calculate the energy dissipated in one cycle. (c) What is the average power input? d) Graph the energy and energy dissipated versus time. Consider a damped oscillator with m = 0.2 kg, k = 100 N/m, and b = 5 N-s/m.
