Daredevil Danny was cliff jumping. He jumped off a cliff that was 1 4 . 2 14.214, point, 2 meters above the surface of the water
iragen [17]

<em>Question:</em>

<em>Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the  water. At the end of his jump, Danny was 2.3 meters below the surface of the water. </em>

<em>The following equation describes this situation  14.2 + (-16,5) = -2.3 .</em>

<em>What does -16.5 tell us?</em>

<em></em>

Answer:

The displacement between his current position and his initial position

Step-by-step explanation:

Given

Initial\ Position = 14.2m

Final\ Position = -2.3m

14.2 + (-16.5) = -2.3

Required

What does -16.5 represents?

<em>To understand this, we need to first calculate the displacement between his initial and final position</em>

<em></em>

Displacement = Final\ Position - Initial\ Position

Displacement = -2.3m - 14.2m

Displacement = - 16.5m

<em>So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)</em>
