To find: the weight on Pike’s Peak.
(a)
Answer to Problem 34AYU
The weight on Pike’s Peak is 5.85 pounds.
Explanation of Solution
Given information:
If an object weights
If Amy weights 120 pounds at sea level, and Pike’s Peak which is 14110 feet above sea level.
Calculation:
Substitute
Therefore the weight on Pike’s Peak is 5.85 pounds.

(c)
To create: a table with
(c)
Answer to Problem 34AYU
The above table we can see that the as height change from 0 to 5 miles weight change from 120 to 119.7 or difference is 0.3.
Explanation of Solution
Given information:
If an object weights
If Amy weights 120 pounds at sea level, and Pike’s Peak which is 14110 feet above sea level.
Calculation:
Table with
From the above table we can see that the as height change from 0 to 5 miles weight change from 120 to 119.7 or difference is 0.3.
(d)
To find: the height that A will weight 119.95 pounds.
(d)
Answer to Problem 34AYU
At height 0.84 A weights 119.95 pounds.
Explanation of Solution
Given information:
If an object weights
If Amy weights 120 pounds at sea level, and Pike’s Peak which is 14110 feet above sea level.
Calculation:
Substitute
Therefore at height 0.84 A weights 119.95 pounds.
(e)
Whether the answer to part (d) seem reasonable.
(e)
Answer to Problem 34AYU
Explanation of Solution
Given information:
If an object weights
If Amy weights 120 pounds at sea level, and Pike’s Peak which is 14110 feet above sea level.
Calculation:
Yes. From the table we can see that 119.95 are between 0.5 and 1. Therefore 0.84 is reasonable.
