Math Problem Statement
A ball is thrown from a height of 217 feet with an initial downward velocity of 17 ft/s. The ball's height h (in feet) after t seconds is given by the following. h= 217 - 17t - 16t^2 How long after the ball is thrown does it hit the ground? Round your answers) to the nearest hundredth. (If there is more than one answer, use the "or" button.).
