A pendulum consists of a cylinder (bob) hanging from a string. Release the cylinder from a known height H and measure its speed v at the bottom of its swing using the photogate; enter those values in the table below. Use the values of H and v to calculate the acceleration of gravity, g. Repeat several times, and find the average value of g. Advice Use the positions of the CM of the bob to measure H

The pendulum of a clock consists of a mass of 0.20 kg hanging from a thin rod. The amplitude of the pendulum swing is 3.0 cm. The clock is driven by a weight of mass 4.5 kg that falls a distance of 0.95 m over a period of 8 days. Assuming the pendulum to be a simple pendulum of length 0.75 m, show that the Q-value of the clock is approximately 70. (Assume g = 9.81 m s−2.)

A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.78 m. With the string hanging vertically, the object is given an initial velocity of 2.9 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle θ with its initial vertical orientation and then swings...

A pendulum is made from 500g ball hanging from 1.50m long string, you can assume that the string is massless. The ball is initially held at a height that is 1.30m above the ground. Upon release, you see that the ball reaches a maximum height of 0.60m above the ground before swinging back. How much energy must have been transformed to thermal energy?

pendulum of mass m= 0.8 kg and length l=1 m is hanging from the ceiling. The massless string of the pendulum is attached at point P. The bob of the pendulum is a uniform shell (very thin hollow sphere) of radius r=0.4 m, and the length l of the pendulum is measured from the center of the bob. A spring with spring constant k= 7 N/m is attached to the bob (center). The spring is relaxed when the bob is...

A pendulum consists of a 5.2 kg ball suspended by a 1.3 m length of string with negligible mass and is initially at rest. A 4.4 g bullet travelling at 680 m/s is fired horizontally into the ball and is lodged there. The ball and bullet rise together to a maximum height of h. How long does it take from the moment of impact for the ball to first reach its maximum height?
