You can put this solution on YOUR website! A rock is thrown upward with a velocity of 25 meters per second from the top of a 33 meter high cliff, and it misses the cliff on the way back down. When will the rock be 9 meters from the water, below?
---------------
Using 10 m/sec/sec for gravity:
h(t) = -5t^2 + 25t + 33, h in meters, t in seconds
-----
-5t^2 + 25t + 33 = 9
Solve for t
