Hey, I have this hw question that's really confusing me, any help would be appreciated. An object is fired upwards with an initial velocity of 112 feet per second. It's bright, in feet above the ground, as a function of time, in seconds since it was fired, is given by the equations 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!!
