Answer:
The object will hit the ground after 9 seconds.
Step-by-step explanation:
We are given the function:
Where <em>h</em> is the height of the object after time <em>t</em>, <em>v</em>₀ is the initial velocity, and <em>h₀</em> is the initial height.
An object is thrown upwards from a height of 720 feet and an initial velocity of 64ft/s. We can to determine how long it will take for the object to reach the ground.
Hence, <em>h₀ </em>= 720 and <em>v₀</em> = 64. Substitute:
When the object reaches the ground, its height <em>h</em> above the ground will be zero. In other words:
Solve for <em>t: </em>

<em />
Since time cannot be negative, we can ignore the first solution.
In conclusion, the object will hit the ground after 9 seconds.
