Pitanje 5

A waterfall has a height of 1500 feet. A pebble is thrown upward from the top of the falls with an initial velocity of 12 feet per second. The height of the pebble h in feet after t seconds is given by the equation h(t)=−16t^{2}+12t+1500. How long after the pebble is thrown will it hit the ground?
You do not need to convert your square root expression into decimal form. You may leave your answer as x= \frac{-b \pm \sqrt{\textrm{something}}}{2a}.
