A simple pendulum can be used to measure gravitational acceleration. A geophysicist measures the frequency of a 0.22 m long simple pendulum to be 0.57 Hz at a particular location on Earth. What is the gravitational acceleration at that location?

A glider attached to one end of a string oscillates given by the displacement function . What is the displacement of the mass after 1.52 seconds?

Rick wants to know Morty's mass in space. He conducted an experiment by attaching an empty chair to a spring and set it to oscillate, and measured the time after one cycle. Afterwards, he asked Morty to sit on this chair not letting his feet touch the ground, then measured the time after one vibration. Calculate Morty's mass by referring to the data gathered by Rick below:

Empty chair

Time after one cycle: 0.65

Mass: 16.97

Morty sitting on the chair

Time after one cycle: 1.93

Mass: ?

A glider attached to one end of a string oscillates given by the displacement function . What is the velocity of the mass after 1.4 seconds?

Juan wants to know the height of a museum. Inside the museum, he notices a very long simple pendulum extending from the ceiling and almost touching the floor. Remembering his lessons in physics, he realizes that he can estimate the height of the museum from the period of the pendulum’s oscillation. If the pendulum undergoes one complete oscillation in 22.99 seconds, how tall is the tower?

In his garage, Rick conducted an experiment to teach Morty how to calculate a spring's force constant. He attached an air track glider to the end of an ideal spring of neglible mass and set it to oscillate.He then asked Morty to measure the time it takes to pass through the equilibrium point and then the second time it pass through the same point. Below are the data gathered by Morty.

• m= 0.53
• t=1.2

Based on the above observation, what is Morty's calculation of spring's force constant?

A 0.38-kg glider is attached to a horizontal spring with stiffness of 130 N/m. If the equilibrium position is at x = 0, what is the acceleration of the glider at x = 0.12 m? 

A horizontal spring (k=400N/m) with a mass of 0.70kg attached to it's undergoing simple harmonic motion. Calculate the(a) period of oscillation, (b) frequency, and (c) angular frequency of the oscillator

3.) Two spherical objects have masses of 3.1 x 10⁵ kg and 6.5 x 10³ kg. The gravitational attraction between them is 65 N. How far apart are their centers?

2.) A 2 kg object is located at a distance of 6.2x10⁵ m from the center of a larger object whose mass is 6.0x10²² kg. What is the size of the force acting on the smaller object?
