a.
Answer to Problem 28E
Explanation of Solution
Given information:
You are holding one of the tethers attached to the top of a giant character balloon that is floating approximately
Find an equation for the length
Calculation:
We shall use the fact that the height of the giant balloon from top to bottoms is
Let, the angle of elevation from the person to the top of the balloon be
From the figure in right
Length
Now, in right
Hence,
