a.
To find : A MIR take about 200 minutes to reach the lowest point to which it can dive. What is its elevation at that time?
a.

Answer to Problem 27E
The elevation at the lowest point after 200 minutes is
Explanation of Solution
Given information :
MIR takes about 200 minutes to reach lowest point to which it can dive.
Calculation :
Since, as a MIR dives its elevation changes by
Therefore,
In 200 minutes the elevation at the lowest point is
Thus, the elevation at the lowest point is
b.
To find : How long would a MIR take to dive to 100 feet below the sea level.
b.

Answer to Problem 27E
It would take 10 minutes for MIR to dive 1000 feet below the sea level.
Explanation of Solution
Given information :
The elevation of MIR changes by
Calculation :
Since, as a MIR dives its elevation changes by
Therefore,
Time taken by MIR to dive to 1000 feet below the sea level is the quotient of
Thus, it would take 10 minutes for MIR to dive 1000 feet below the sea level.
