Spring Potential Energy Example (Mistake in Math)

Lecture Description

A spring, a frozen loop-d-loop and more! (See if you can find the mistake I made and get the right answer!).

Course Description

Projectile motion, mechanics and electricity and magnetism. Solid understanding of algebra and a basic understanding of trigonometry necessary.
