Question 1185880
An object is thrown upward from a height of 80 ft. The initial velocity of the object is 64 ft per second. If the height h (in feet) is h=-16 +64t+80, where t is time in seconds, when will the object reach the ground?
----------------

"If" - If the height h (in feet) is h=-16 +64t+80
==========================
It's h=-16t^2 + 64t + 80
---
-16t^2 + 64t + 80 = 0
Solve for t, ignore any negative values.
