47. A 10.6-kg object oscillates at the end of a vertical spring that has a spring constant of 2.05 x 104 N/m. The effect of air resistance is represented by the damp- ing coefficient b = 3.00 N s/m. (a) Calculate the frequency of the damped oscillation. (b) By what per- centage does the amplitude of the oscillation decrease in each cycle? (c) Find the time interval that elapses while the energy of the system drops to 5.00% of its initial value.

A mass of 16 kilograms is suspended from a spring with spring constant 7 Kg/sec^2. The damping constant is 2 Kg/sec and the spring is subject to an external force F(t)= 3cos(9t) Newtons. The motion of the mass eventually settles down to a periodic oscillation. What is the period (in sec) of this periodic oscillation? 2 9.
