Concept explainers
To find: the height from which the object will fall in 8 seconds.
Answer to Problem 86E
Object falls 1024 feet in 8 seconds.
Explanation of Solution
Given information:
During the first second of fall, the object falls 16 feet; during the second, it falls 48 feet; during the third second, it falls 80 feet; and during the fourth second, it falls 112 feet.
Concept used:
An arithmetic sequence of n terms, has the form
That is
Common difference can be defined by d .
nth term of the arithmetic sequence has the form
Where
Sum of an arithmetic finite sequence has the form
Here, n is number of terms,
Calculation:
First second of object falls
Second of object falls
The common difference between these seats is
The objective falls in 8 second by using formula,
Hence object falls in 8 seconds is 1024.
