Old Faithful in Yellowstone Park is probably the world’s most famous geyser. Old Faithful sends a stream of boiling water into the air. During the eruption, the height h (in feet) of the water t seconds after being forced out from the ground could be modeled by h=-16t^2+170t
what is the initial velocity of the boiling water
what is the maximum height of the boiling water
how long is the boiling water
