Answer: 64 ft
Step-by-step explanation:
We are given the following equation that models the baseball's parabolic path:
(1)
Where:
is the ball maximum height
is the time
is the initial height
With this information the equation is rewritten as:
(2)
Now, we have to find , and this will be posible with the following formula:
(3)
Where:
is the final velocity of the ball at the point where its height is the maximum
is the acceleration due gravity
Isolating :
(4)
(5)
(6)
Substituting (6) in (2):
(7)
Finally:
This is subtraction property of equality.
