Textbook QuestionYou pull a simple pendulum 0.240 m long to the side through an angle of 3.50° and release it. How much time does it take the pendulum bob to reach its highest speed?1806views
Textbook Question(II) A simple pendulum is swinging with amplitude equal to 8.5°. With what angle should it swing if its total energy is to be doubled?1573views
Textbook QuestionA clock pendulum oscillates at a frequency of 2.5 Hz. At t = 0, it is released from rest starting at an angle of 12° to the vertical. Ignoring friction, what will be the position (angle in radians) of the pendulum at t = 0.25 s?1424views
Textbook Question(III) A simple pendulum oscillates with an amplitude of 10.0°. What fraction of a period does it spend between +8.0° and -8.0°? Assume SHM.1523views
Textbook QuestionThe length of a simple pendulum is 0.72 m, the pendulum bob has a mass of 295 g, and it is released at an angle of 12° to the vertical. Assume SHM. With what frequency does it oscillate?1239views
Textbook Question(II) A musician wishes to construct a metronome based on a simple pendulum design where a “beat” is sounded when the bob reaches each opposite extreme of its swing. How long must the pendulum be so that this metronome is set for 104 bpm (bpm = beats per minute)?1619views
Textbook QuestionInterestingly, there have been several studies using cadavers to determine the moments of inertia of human body parts, information that is important in biomechanics. In one study, the center of mass of a 5.0 kg lower leg was found to be 18 cm from the knee. When the leg was allowed to pivot at the knee and swing freely as a pendulum, the oscillation frequency was 1.6 Hz. What was the moment of inertia of the lower leg about the knee joint?1395views
Textbook QuestionA uniform rod of length L oscillates as a pendulum about a pivot that is a distance x from the center. For what value of x, in terms of L, is the oscillation period a minimum?2080views
