A waterfall has a height of 1500 feet. A pebble is thrown upward from the top of the falls with an initial velocity of 20 feet per second. The height, h, of the pebble after t seconds is given by the equation h=-16t²+20t+1500. How long after the pebble is thrown will it hit the ground? seconds after it is thrown. The pebble will hit the ground about
