Question 1137058
 In object is thrown off a platform  that is 15 feet high with an initial velocity of 8.5 feet/S. What function models the height H open [sic]?? the object after T seconds?
---------------
The commonly used value for gravity on Earth is 32 ft/sec/sec
Sometimes 32.2 is used.
=============
---> h(t) = -16t^2 + 8.5t + 15
The 8.5 is positive if it is thrown upward, and negative if downward.
