Question

if an object is propelled upward from a height of s feet at an initial velocity of v feet per second, then its height h after t seconds is given by the equation h=-16t^2+vt+s where h is in feet. If the obct is propelled from a height of 12 feet with an initial velocity of 64 feet per second, its height h is given by the equation h=-16t^2+64+12

Answer 1

What's the question here? are we filling in the equation?

Answer 2

Oh I am sorry the question was after how many seconds is the height 72 feet

Answer 3

Can we move the conversation to your post in the mathematics section please? Just to try and keep things on topic.
