Maximizing Safety: Pendulum Swing Help for Jack and His 653 N Weight

In summary, Jack weighing 653 N swings from a cliff using a 26 m long vine. The maximum descent is 3.2 m and the vine will break if the force exceeds 950 N. The vine does not break. The greatest force on the vine during the swing is 653 N. The angle at which the vine would break, if it were to break, should be in the homework section.

Jack, who weighs 653 N, swings from a cliff at the end of a convenient vine that is 26 m long. From the top of the cliff to the bottom of the swing, he descends by 3.2 m. The vine will break if the force on it exceeds 950 N.

(a) Does the vine break? yes / no
(b) What is the greatest force on the vine during the swing? ____Newtons
(c) At what angle does it break, if it breaks?

1. What is a pendulum swing?

A pendulum swing is a motion in which an object (called the pendulum) swings back and forth between two fixed points due to the force of gravity. This motion is repetitive and can be used to measure time.

2. How does a pendulum swing work?

A pendulum swing works because of the force of gravity. As the pendulum swings back and forth, it gains and loses potential energy due to its changing height. This energy is then converted into kinetic energy, causing the pendulum to continue swinging.

3. What factors affect the swing of a pendulum?

The swing of a pendulum is affected by several factors, including the length of the pendulum, the mass of the pendulum, and the angle at which it is released. Other factors such as air resistance and friction can also affect the swing.

4. How is a pendulum swing used in science?

A pendulum swing is used in science for various purposes, such as measuring time, determining the value of gravitational acceleration, and studying the relationship between potential and kinetic energy. It is also used in experiments to demonstrate concepts of physics, such as energy conservation and harmonic motion.

5. Can a pendulum swing be used for accurate timekeeping?

Yes, a pendulum swing can be used for accurate timekeeping. In fact, pendulum clocks were the most accurate timekeeping devices for centuries before the invention of the quartz clock. The length of the pendulum is carefully adjusted to ensure that each swing takes exactly the same amount of time, making it a reliable timekeeping instrument.
