A cannonball fired out to sea from a shore battery follows a parabolic trajectory given by the graph of the equation h(x) = 9x - 0.01x2 where h(x) is the height of the cannonball above the water when it has traveled a horizontal distance of x feet. h(x) (a) What is the maximum height that the cannonball reaches? (b) How far does the cannonball travel horizontally before splashing into the water
