SUMMARY
The Pendulum Problem involves calculating the speed of a ball at an angle θ using the principles of energy conservation. The initial kinetic energy (Ek) is derived from the height of the pendulum when released, which can be expressed as potential energy (PE = mgh) at angle θ. By determining the height of the ball at this angle, one can calculate the kinetic energy and subsequently the speed (v) as a function of mass (m), gravitational acceleration (g), string length (L), and angle (θ).
