Question

Using the graph of the eagle's descent, how fast is the eagle descending?

Answer 1

1) Considering the graph, we can find out how fast the eagle is descending by locating two points:

0. The initial point at (0,20)

,

1. The final point at (6, 0)

Notice that the graph is time for the x-axis, and height (for the y-axis) so the first value refers to time, and the second to height. In second and feet.

2) Since the Velocity is given by

`\begin{gathered} V=|\frac{Dis\tan ce}{\text{Time}} \\ V=|(0-20)/(6-0)| \\ V=|(-20)/(6)| \\ V=3.33\text{ ft/s} \end{gathered}`

Since the eagle is descending the slope is negative, but as we want the Velocity we keep with the absolute value of that. So the eagle is descending at a rate of approximately 3.33 feet per second
