jasper hung a 1.7kg wind chime on his balcony. What is the tension on the string he used to hang the wind chime?

An astronaut lands on a foreign world and wants to measure the local gravitational field strength where he lands. He takes a 0.31m length pendulum and holds it 4 degrees from the vertical. He then releases the pendulum and measures that it takes 7.85 seconds for the pendulum to swing through 10 cycles of swing. What is the gravitational field strength on the planet?

You pull a simple pendulum 0.240 m long to the side through an angle of 3.50° and release it. a. How much time does it take the pendulum bob to reach its highest speed? b. How much time does it take if the pendulum is released at an angle of 1.75⁰ instead of 3.50°?

A mass of 70.0 g is hung on the end of a string that is 2.00 m in length. It is given an initial speed of 1.20 m/s and released while at an angle of 30.0 degrees from its equilibrium position.    Part A What is the speed of the mass at its lowest point? Part B What is the speed of the mass when \thetaθ = 15.0 degrees? Part C What is the tension in the string when the mass is at its lowest point?

A pendulum is 0.341m long and has a period of 3.207s. The pendulum is on an unknown planet. What is the gravity of the unknown planet in m/s2?

A 30.0-kg block is resting on a flat horizontal table. On top of this block is resting a 15.0-kg block, to which a horizontal spring is attached, as the figure illustrates. The spring constant of the spring is 271 N/m. The coefficient of kinetic friction between the lower block and the table is 0.615, and the coefficient of static friction between the two blocks is 0.852. A horizontal force is applied to the lower block as shown. This force is increasing in such a way as to keep the blocks moving at a constant speed. At the point where the upper block begins to slip on the lower block, determine (a) the amount by which the spring is compressed and (b) the magnitude of the force F. www 15.0 kg 30.0 kg F

A spring has a length of 0.260 m when a 0.300 kg mass hangs from it, and a length of 0.750 m when a 2.80 kg mass hangs from it.   What is the force constant (in N/m) of the spring? What is the unloaded length (in m) of the spring?

Asimple pendulum which has a frequency of 2.5 Hz.on the surface of the Earth is used by an astronaut visiting a newly discovered planet. On that planet's surface, the pendulum swings with a frequency of 1.6 Hz. How large is the gravitational acceleration of that planet?
