(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A pendulum consists of a mass on a 50 cm long string. It is being held stationary at a 30°angle with the vertical. After release, how fast will it be going at the bottom? (Hint: Use trigonometry to find how high the ball is initally)

2. Relevant equations

Ek = 1/2mv^2 for sure to find the velocity

Eg = mgh

3. The attempt at a solution

I'm basically brain-dead on this question, I don't know where to start.
