a long pendulum has a period of 10s. if the bob is displaced 2m from equilibrium and released, approximately how long will it take to move 1m?
Problem 9A We showed that the length of the pendulum of period 2.000 seconds on the Earth’s surface was 0.99396 meters. What period would this same pendulum have on the surface of Mars? What length would the pendulum be in order to have a period of 2.000 seconds? Problem 9B Suppose the simple pendulum from Problem 9A is mounted in a rocket (on Earth) with an initial mass of 1500 kg. What thrust at launch is required to change the...
A "seconds pendulum" is one that moves through its equilibrium position once each second. (The period of the pendulum is precisely 2s. The length of a seconds pendulum is 0.992 7 m at Tokyo, Japan, and 0.994 2 m at Cambridge, England. What is the ratio of the free-fall accelerations at these two locations? A simple pendulum makes 120 complete oscillations in 3.00 min at a location where g = 9.80 m/s^2. Find (a) the period of the pendulum and...

The cylinder is displaced 0.18 m downward from its equilibrium position and is released at time t = 0. Determine the displacement y and the velocity v when t = 2.2 s. The displacement and velocity are positive if downward, negative if upward. What is the magnitude of the maximum acceleration? K= 147 N/m Equilibrium position m = 4.0 kg Answers: When t = 2.2 s: ya 0.129 When t = 2.2 s: V =...
Problem 11.25 If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it oscillates. Suppose it is displaced 0.128 m from its equilibrium position and released with zero initial speed. After 0.830 s , its displacement is found to be 0.128 m on the opposite side and it has passed the equilibrium position once during this interval. Part A Find the amplitude of the motion. A = m SubmitMy AnswersGive Up Part B...
A 4.0 kg mass is placed on a vertical spring, and displaced from equilibrium by 0.25 m, and released from rest. It is observed that the mass/spring system oscillates with respect to time t, according to the function y(t)=(0.25m) cos〖(4πt).〗 What is the period of oscillations?
A pendulum has a period of 1.8 s. The pendulum is released from rest at an angle θ = 13° What is its maximum angular acceleration?
A block attached to a spring is displaced from equilibrium to the position x = + 1.1 m and released. The period is 4.5 s . At what positions and times during the first complete cycle do the following conditions occur. a) | v | = 0.5vmax , Where vmax is the maximum speed? First position:? First time: ? Second position: ? Second time: ? Third position: ? Third time: ? Fourth position: ? Fourth time: ?
The simple pendulum is often given as an example of simple harmonic motion. In this problem will will see how accurate this is. (a) Imagine a vertical pendulum of length l and mass m. Using the forces on the pendulum and applying Newton’s second law, obtain a differential equation in terms of θ (the angle with respect to the vertical axis) and its time derivatives. Please work in polar coordinates. (b) Show that in the limit where θ is small...
