## Homework Statement

The pendulum is started swinging from a height of 0.3000 m above its rest position and allowed to swing freely back and forth. If 1.00% of the bob's energy is lost due to friction each swing, to what maximum height will the bob swing at the end of its fourth swing?

## Homework Equations

I cannot even begin to think of any

## The Attempt at a Solution

h=0.3000m

energy lost=1.00%/swing

max h=?

PEi + KEi = PEf + KEf + HE
