A toy rocket is shot vertically into the air from a 80-foot platform. The height, h(t) in feet, of the rocket above the ground after t seconds is modeled by h(t) = -16t^2 + 128t + 80. (Give solutions accurate to two decimal places. No credit will be awarded for a calculator-only solution.) (a) How high is the rocket after 3 seconds? (b) How many seconds will it take the rocket to reach its maximum height? (c) What is the maximum height of the rocket? (d) How long will it take the rocket to reach the ground?
