Asked by Shelby
A toy rocket is shot vertically into the air from a launching pad 9 feet above the ground with an initial velocity of 80 feet per second. The height h, in feet, of the rocket above the ground at t seconds after launch is given by the function h(t)=−16t2+80t+9. How long will it take the rocket to reach its maximum height? What is the maximum height?
