Consider a simple pendulum (point mass bob) 0.50 mlong
Chapter 14, Problem 14.69(choose chapter or problem)
Consider a simple pendulum (point mass bob) 0.50 mlong with a Q of 350. (a) How long does it take for theamplitude (assumed small) to decrease by two-thirds? (b) Ifthe amplitude is 2.0 cm and the bob has mass 0.27 kg, whatis the initial energy loss rate of the pendulum in watts? (c) Ifwe are to stimulate resonance with a sinusoidal drivingforce, how close must the driving frequency be to thenatural frequency of the pendulum (give A/ = / - / 0)?
