Hello! I have this math question for homework that is really confusing me. Any help would be appreciated. An object is fired upwards with Ana initial velocity of 112 feet per second. Its height, in feet above the ground, as a function of time, in seconds since it was fired, is given by the equation h(t) = -16t^2 + 112t.

(a) At what height was the object fired?
(b) Algebraically, find the time that the rocket reaches its greatest height and the maximum height
(c) Algebraically, determine the time when the rocket reaches the ground

Thanks a million ~~
