Question

36. A shark is being tracked with afin tag. The shark is swimmingsteadily 32 feet below thesurface before ascending 5 feetand quickly descending 13 feet.What is the total change in theshark's position underwater?

Answer 1

The initial level is h0=32 feet below the surface.

The final level is

`h_1=h_0+5-13=32+5-13=24`

We can calculate the change in level as:

`\Delta h=h_1-h_0=24-32=-8`

The total change is 8 feet more deep (-8 in reference to the surface level)
