Algebra

The height h(t) measured in feet of an object dropped by an astronaut on the moon can be approximated by h(t) = h0 (0 on the bottom) - 2.7t^2, where h0 is the height from which the object was dropped. About how long would it take an object to fall to the moon (h = 0) if it were dropped by an astronaut from a height of 6 feet?
