**[SOLVED] Pendulum - Kinetic Energy at Lowest Point?**

1. The Problem Statement:

A pendulum of length L= 1.0 m with an attached bob of mass m= 0.2 kg is released from a point where the cord makes an angle of 30 degrees with the vertical. The kinetic energy of the bob at its lowest point is...?

a. 2.0 J,

b. 1.7 J,

3. 1.1 J,

4. 1.0 J,

5. 0.26 J

## Homework Equations

I believe Relevant equations include:

(1/2)mv^2 -- kinetic energy

(mgy) -- potential energy

## The Attempt at a Solution

I know that at the lowest point in the pendulum, it is the highest speed. There is no potential energy. But, how do I get the value for velocity?
