For this case, the we have that the generic equation of motion is:
We have then:
Where,
- <em>g: acceleration of gravity
</em>
- <em>vo: initial speed
</em>
- <em>yo: initial height
</em>
First equation:
Second equation:
For same height we have:
Clearing time:
Answer:
it takes 18.31s for the two window washers to reach the same height
0.35*1430=500.5, anywhere up from 1,430 pounds will equate to over 500$
