Water that is sprayed upward from a sprinkler with an initial velocity of 20 m /s can be approximated by the function y = -5x2 + 20x, where y is the height of a drop of water x seconds after it is released. Graph this function on your own paper. Then, use your graph to determine the time it takes a drop of water to reach its maximum height, the water's maximum height, and the time it takes the water to reach the ground.
What is the time to reach the maximum height?
