Answer:
8.36
Step-by-step explanation:

 
        
             
        
        
        
(5)(5)(5)(5)(5)(5)(5)(5)(5)(5)(5)
5^11
That is two of the three but I'm not quite sure if there is a third.
        
                    
             
        
        
        
When
the ball is in the ground, its height is basically equal to zero thus making
our equation,
<span>    -16t^2 + 272t + 1344 = 0</span>
Simplifying
the equation will give us,
<span>  - t^2 + 17t + 84 = 0 or t^2 – 17t – 84 = 0</span>
Factoring
out the equation will give us,
<span>   (t – 21)(t + 4) = 0</span>
Thus,
t = 21 or t = -4. -4 is an extraneous root. Thus, the answer is t = 21.
<span>Answer:
21 seconds</span>
