One breezy evening, a person decides to enjoy the climate by taking a stroll outside. After a few minutes of walking, he crosses a lamp post. If the person is 80 \(cm\) in height, and they are walking at a speed of 1 \(m/s\), find the length of the person's shadow above the ground after 6 seconds. Also, the length of the lamp post is 3.2 \(m\) above the ground.
The length of the shadow is \(m\) above the ground.
[Note: Round off the answer obtained to one decimal places]
