A rocket is propelled upward from the top of a building 220 feet tall at an initial velocity of 136 feet per second. The function that describes the height of the rocket in terms of time, t, is given below. Determine the time at which the rocket reaches its maximum height. s ( t ) = − 16 t 2 + 136 t + 220 {“version”:”1.1″,”math”:”s(t)=-16t^2+136t+220″}
