Answer:
[tex]3,072\ ft[/tex]
Step-by-step explanation:
we have
[tex]h(t)=-16t^{2} +192t+2,560[/tex]
where
h -----> is the height in feet of the rock
t -----> the time in seconds
For [tex]t=8\ sec[/tex]
substitute the value of t in the function and find the value of h
[tex]h(8)=-16(8)^{2} +192(8)+2,560=3,072\ ft[/tex]
