What is the period of a pocket watch of mass m = 1.20 kg and length L = 0.356 m (14 inch), in second? Use g = 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A "seconds" pendulum is one that goes through its equilibrium position once each second. (The period of the pendulum is 2.000 s.) The length of a seconds pendulum is 0.9927 m at Tokyo and 0.9942 m at Cambridge, England. What is the ratio of the free-fall accelerations at these two locations? (Give your answer to at least 4 decimal places.) Cambridge/Tokyo   = ?

It is said that Galileo discovered a basic principle of the pendulum - that the period is independent of the amplitude - by using his pulse to time the period of swinging lamps in the cathedral as they swayed in the breeze. Suppose that one oscillation of a swinging lamp takes 9  s. How long is the lamp chain (in meters)?

You have carried out an experiment to investigate the effect of the length of a pendulum on the time period of oscillation. Theory says that the pendulum should follow the rule  T= 2π√L/g Where T is the time period (seconds) L is the length of the pendulum (metre) G is the acceleration due to gravity (g = 9.81 m/s²) Calculate the expected percentage error in the time period calculation if your measurement of length is 4% high.

What is the mass of an object that is attached to a spring with a force constant of 120 N/m if 14 oscillations occur each 16 s? (Express your answer to two significant figures.)

Note the square of the period of oscillation for a hanging mass of 151.2 g is 0.937s^2..... (calculate it to get more decimals)

A simple pendulum has a length of 120 cm. If it oscillates on Earth, what would be its time period? If it is taken to moon, what will happen to its time period? Gravity on Moon is 1/6th of the Earth. Earth’s gravity is 9.81 m/s^2

An object of unknown mass is attached to an ideal spring with force constant 110 N/m and is found to vibrate with a frequency of 5.50 Hz. Part A Find the period. Express your answer in seconds. Part B Find the angular frequency. Express your answer in radians per second. Part C Find the mass of this object. Express your answer in kilograms.

Two pendulums have the same dimensions (length L) and total mass (m). Pendulum A is a very small ball swinging at the end of a uniform massless bar. In pendulum B, half the mass is in the ball and half is in the uniform bar. Find the period of pendulum B for small oscillations. Express your answer in terms of the variables L, m, and appropriate constants.

One procedure used to determine the mass of astronauts in space consists of in making them oscillate in a spring-mass system. For this a 42.5 kg chair is used connected to a spring. When the chair is empty it takes 1.3 s to complete one swing. When the astronaut sits in the chair it takes the system 2.54 s to complete one oscillation. Determine the mass of the astronaut.

On a certain planet, a simple pendulum of length 1.4 m makes three complete oscillations in five seconds. Find the gravitational acceleration on such a planet. The results of all problems should be expressed in SI units, unless the problem tells you indicate in other units.
