A rock is thrown upward from the top of a 112-foot high cliff overlooking the ocean at a speed of 96 feet per second. The rock’s height above ocean can be modeled by the equation $H (t) = - 16 t^{2} + 96 t + 112.$

ⓐWhen does the rock reach the maximum height?
ⓑWhat is the maximum height of the rock?
ⓒWhen does the rock hit the ocean?
