Unformatted text preview: The total height is L . Assume no damping. At time t = 0, the cylinder is pushed down a distance B and released. (a) What is the frequency of oscillation? (b) Draw a graph of velocity versus time from t = 0 to t = one period. The correct amplitude and phase should be included. 314. An object of mass 0.2 kg is hung from a spring whose spring constant is 80 N/m. The object is subject to a resistive force given by bv , where v is its velocity in meters per second. (a) Set up the differential equation of motion for free oscillations of the system. (b) If the damped frequency is ·¸ ´µ of the undamped frequency (when b = 0), what is the value of the constant b ? (c) What is the Q of the system, and by what factor is the amplitude of the oscillation reduced after 10 complete cycles?...
