Math Problem Statement
Determine the maximum height for an object launched with the function h(t)=-16t^2+360t
Solution
To determine the maximum height of an object launched with the function , we need to find the vertex of this parabolic equation, since the vertex will give us the maximum height (as the coefficient of is negative, indicating a parabola that opens downwards).
The vertex form of a parabola is given by the vertex , where . In our case, the function is:
Here, and .
First, find the time at which the maximum height occurs:
Now, substitute back into the function to find the maximum height:
Calculate :
Now substitute and calculate:
Therefore, the maximum height of the object is feet.
