You can put this solution on YOUR website! Please someone help me with this problem: If a stone is tossed from the top of a 170 meter building, the height of the stone as a function of time is given by h(t) = -9.8ft^2 - 10t + 170.
------------
I think you mean
h(t) = -4.9t^2 - 10t + 170 (on Earth)
The -10t means it's tossed downward.
check that, repost
