- A simple pendulum has a period of 2.7 s and an amplitude of 5.0 cm. The mass of the bob is 5 g. Calculate the maximum kinetic energy of the pendulum and give your answer micro Joules (μJ).A student releases the 4kg bob of a 1.92m long pendulum from the position shown. Neglect loss. What is the pendulum's height (h) above its lowest point? unit What is the pendulum's maximum speed during the swing? unit What is the tension in the string at the lowest point? unit C 27°1. A simple pendulum is suspended from the ceiling by means of a string of length 1.14 m. Assume that there is no friction or air resistance. Suppose you were to release the pendulum from rest, starting from an angle of 58.2 degrees with respect to the vertical, as shown. What will be the speed of the pendulum at the instant it swings through its lowest point (that is, when it s momentarily hanging vertically)? 2.28 m/s 3.25 m/s 3.43 m/s 4.73 m/s
- QUESTION 3 This, the length of the pendulum is 1.03 m. Now you start with the pendulum at 28.7 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 47.8 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it? A 2.04 m/s B 2.58 m/s C 1.58 m/s D 3.61 m/sThe pendulum shown in the figure below is released from point A starting from rest. The length of the cord is 75 cm and the mass of the ball is 1 kg. Find the speed of the ball as it passes through point C. Find the speed of the ball at point b.A 1.15 kg mass is attached to a 1.86 m string that is anchored to the ceiling. The mass is pulled back to an initial angle of theta = 65.1 degrees and released from rest. (a) How fast is the ball moving at the bottom of its swing — the position indicated in the figure? (b) What is the tension in the string at the bottom of the swing — the position indicated in the figure?

The vertical axis is set by Ks=4mJ and the mass of the pendulum bob is 0.200 kg. Determine the length of the pendulum in meters. Use g = 9.8 N/kg.A cart with mass m is held at rest against a spring with spring constant k. It is compressed a distance x. When released from rest, it is launched through a frictionless track. It contains a vertical loop 7. with a radius of R. Find the force the track exerts on the cart when the cart goes through the top of the loop in terms of m, k, F, and R and any other constants. R k mA pendulum has a 10 kg bob on a string that is 2 m long. It is raised so that it forms an angle of 90 degrees with it's resting position. (It is horizontal, parallel with the ground).
