h= -16t^2 + 64t +512 how tall is the building

Question

 im confused

Answer 1

Are you saying that the height is a function of time?

 

This looks like the following problem: from the top of a building on Earth, the height above ground of a projectile launched upward at 64 ft/sec is given by the formula for h, in which -16 t² shows the effect of gravity, pulling downwardly, from a building that is 512 ft tall.
