On Mars, gravity is less than it is on Earth. If you were to kick a Mars rock at an initial velocity of 56 feet per second from the top of a 30-foot hill, the rock's height h would be modeled by the equation h = -1.9t^2 + 56t + 30 where t is time in seconds.
A. How high would the rock be after 20 seconds?
B. How high would the rock get?
C. How long would the rock be in the air?
