A rock is thrown upward from the top of a 144-foot high cliff overlooking the ocean at a speed of 128 feet per second. The rock’s height above ocean can be modeled by the equation H(t)=−16t^2+128t+144. When does the rock reach it's maximum height?
What is the maximum height of the rock?
When does the rock hit the ocean?
