A waterfall has a height of 1000 feet. A pebble is thrown upward from the top of the falls with an initial velocity of 24 feet per second. The height, h, of the pebble after t seconds is given by the equation h = - 16t² +24t+1000. How long after the pebble is thrown will it hit the ground? The pebble will hit the ground about seconds after it is thrown.
