A toy rocket is shot vertically into the air from a 3-foot-tall launching pad with an initial velocity of 136 feet per second. Suppose the height of the rocket in feet t seconds after launched can be modeled by the function h(t) = - 16t + Vit+ ho, where vo is the initial velocity of the rocket and he is the initial height of the rocket. How long will it take for to reach its maximum height? What is the maximum height? The rocket will reach its maximum height in second(s)
