Arock is propelled upward from the top of a building 180180 feet tall at an initial velocity of 200200 feet per second. the function that describes the height of the rocket in terms of time t is f (t )equals negative 16 t squared plus 200 t plus 180.f(t)=−16t2+200t+180. determine the maximum height that the rock reaches.
