Answer 1

Question:

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.

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

What does -16.5 tell us?

Answer:

The displacement between his current position and his initial position

Explanation:

Given

`Initial\ Position = 14.2m`

`Final\ Position = -2.3m`

`14.2 + (-16.5) = -2.3`

Required

What does -16.5 represents?

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

`Displacement = Final\ Position - Initial\ Position`

`Displacement = -2.3m - 14.2m`

`Displacement = - 16.5m`

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