Practice Problem: Pendulum Velocity

In this video, a simple pendulum experiment is set up in a garage. The pendulum consists of a 2-meter string and a 0.5 kg ball. The video explores the concepts of potential and kinetic energy, explaining how energy is converted as the pendulum swings. The point of maximum speed is identified as the lowest point of the swing, where kinetic energy is at its peak. The video demonstrates how to calculate the initial potential energy and convert it to kinetic energy to find the velocity at the lowest point, using trigonometry to determine the height of release. The final velocity is calculated to be 4.08 meters per second.

What is the length of the string used in the pendulum?

At what angle is the pendulum released?

What type of energy does the pendulum have just before it is released?

How is the height at the point of release calculated?

What is the final velocity of the pendulum at the lowest point?
