During a relaxed walking pace, a person's leg can be thought of as a physical pendulum of length L that pivots about the hip.  What is the relaxed walking frequency in Hz for a person whose leg is of length 1.138m

A spiral staircase winds up to the top of a tower in an old castle. To measure the height of the tower, a rope is attached to the top of the tower and hung down the center of the staircase. However, nothing is available with which to measure the length of the rope. Therefore, at the bottom of the rope a small object is attached so as to form a simple pendulum that just clears the floor. The period of the pendulum is measured to be 6.10 s. What is the height of the tower? Number Units

Two parakeets sit on a swing with their combined center of mass 12.3 cm below the pivot. At what frequency do they swing?

Atoms in a solid continuously vibrate due to thermal energy. At room temperature, the amplitude of these atomic vibrations is about 1.4 x 10-11 meters, and their frequency is about 1.1 x 1012 hertz. What is the maximum speed of a vibrating atom? Include units in your answer.   PLEASE ANSWER IN HANDWRITING   THANK YOU!!!

If the effective spring constant of a 2000 kg older car (with poor shocks) is 560000N/m, what is the period of its vibration after hitting a bump? What is the effective spring constant of a 10kg, 1.5 m simple pendulum? When a ball is suspended from a spring, the spring stretches by 8 cm. What is the frequency of the ball if it oscillates up and down?

A “seconds” pendulum is one that moves through its equilibrium position once each second. (The period of the pendulum is 2.000 s.) The length of a seconds pendulum is 0.992 7 m at Tokyo and 0.994 2 m at Cambridge, England. What is the ratio of the free-fall accelerations at these two locations?

What is the frequency (in Hertz) of a simple pendulum 1.7 m long in an elevator accelerating upwards at a rate of 9.6 m/s2? Final answer in one decimal place.

A pendulum is created with a string of length L, fixed at the top. A ball with mass m is fastened to the bottom. The ball is pulled to the side through an angle theta anrd released. What is the speed of the ball at lowest point? L=1.90 Theta=29.0 Mass=600kg

A spring is mounted vertically on the floor. The mass of the spring is negligible. A certain object is placed on the spring to compress it. When the object is pushed further down by just a bit and the released, one up/ down oscillation cycle occurs in 0.230s. However, when the object is pushed by 5.32 x 10-2 m from unstrained position to point P and then released, the object flies entirely off the spring. To what height above point P does the object rise in the absence of air resistance?

A 0.600 m long pendulum is used to determine the acceleration due to gravity on a distant planet. If 20 complete oscillations are completed in 35.5 s, the acceleration would be?
