Angel falls in Venezuela is the tallest waterfall in the world. Water falls uninterrupted for 2421 feet before entering the river below. The height h above the river in feet of water going over the edge of the waterfall is modeled by h(t)=-16t^2+2421, where r is the time in seconds after the initial fall.
Estimate the time it takes for the water to reach the river. Round your answer to the nearest tenth of a second.
