A grandfather clock uses a pendulum with period 2.5 s to keep time. In one such clock, the pendulum bob has a mass 250g; the pendulum is set into oscillation by displacing it 35mm to one side. a) what is the length of the pendulum? b) Does the initial displacement satisfy the small angle approximation?

A certain simple pendulum consists of a small 750.0 ? bob that swings on the end of a 25.0 ?? string. The small amplitude of the oscillations of this pendulum decays to half its original value after 45.0 oscillations. The angular position of the pendulum as a function of time, ?(?), can be expressed as follows. ?(?) = ??0 ? − ??/2m cos(? ′ ? + ?) ??0 is the original angular amplitude. ? is the time, and ? is...

A large pendulum swings in the lobby of the United Nations building in New York City. The pendulum has a 91-kg gold-plated bob and a length of 22.9 m. Assume g = 9.81 m/s2.How much time does it take for the bob to swing from its maximum displacement to its equilibrium position?

Consider a simple pendulum consisting of a massive bob suspended from a fixed point by a string. Let T denote the time (period of the pendulum) that it takes the bob to complete one cycle of oscillation. How does the period of the simple pendulum depend on the quantities that define the pendulum and the quantities that determine the motion? [You need to perform a dimensional analysis to solve this one. Start by assuming T = k Inmpgq, where k...

A 1.8 kg pendulum bob hangs from a 2 meter string. It is pulled
to the side, position A, so that the bob is 121 cm (h on the
sketch) above the lowest position, position C. The bob is released
and begins to swing. See below.
What is its potential energy after it has swung to position B,
34.0 cm below the starting point?
And, how fast is it moving at that point?

The figure below shows a "conical pendulum", in which the bob
(the small object at the lower end of the cord) moves in a
horizontal circle at constant speed. (The cord sweeps out a cone as
the bob rotates.) The bob has a mass of 0.050 kg, the string has
length L = 0.66 m and negligible mass, and the bob follows a
circular path of circumference 0.86 m.
