Question
Assume g=8.808 m/s^2
Two pendula of length 1.00m are set into motion at the same time. One pendulum has a bob of mass 0.050kg and the other has a mass of 0.100kg. A) What is the ratio of the periods of oscillation? B) What is the period of oscillation if the initial angular displacement is small? C) What is the period of oscillation if the initial angular displacement is 60.0 degrees? Hint: use the above equation, but carry the series out to only three terms.
A wrecking ball swings through its equilibrium position 10.0 times in 50.0 seconds. How many complete oscillations does the wrecking ball make in the 50.0 seconds? What is the period of oscillation for this pendulum? Determine the length of the cable supporting the wrecking ball.
A 100.0 kg mass rests on a vertical spring with a spring constant of k=500.0 N/m. What is the displacement of the spring?
