To calculate:The equation that depicts that the maximum range of the projectile

Answer to Problem 138RE
The maximum range if the ball is thrown at
Explanation of Solution
Given information:
Here, the maximum range of the projectile
Also, the maximum range of
New velocity is
Formula used:
For 2 variables say,
Which can be written as:
Where
Similarly the statement
Which can be written as:
Where
Calculation:
As the maximum range of the projectile
For 2 variables say,
Which can be written as:
Where
Hence, this variation can be expressed as follows:
Where
It is also given
Put these values in
Therefore, the proportionality constant
Therefore,
Now for new velocity of
Replace the value of
Thus, the maximum range if the ball is thrown at
