The maximum speed of a pendulum is .55 m/s. if the pendulum makes a maximum angle of 8 degrees with the vertical what is the length of the pendulum? The back of the book says that the answer is 1.59m.

## Homework Equations

Its in the chapter of our book entitled 'Conservation of Energy' so I'm assuming I use the equations dealing with Kinetic & Potential Energy

## The Attempt at a Solution

I tried using 1/2mv^2 = mv^2 / r but i got r = 2m for an answer and the back of the book says its 1.59m so that can't be the right equation
