Answer:
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
Step-by-step explanation:
Given that,
A ball is thrown vertically upward. After t seconds its height is given by the function
where h is height in feet.
Maximum value:
Given function f(x)= at²+bt+c.
- Find the value
- Putting
in the given function.
- The maximum value of the given function is
.
Here a= -16 , b=56 and c=0
The ball attains its maximum height when s.
Putting the value of t in the given function
=49 feet
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
