Launching a rocket A small rocket is launched vertically
Chapter 6, Problem 63E(choose chapter or problem)
Launching a rocket A small rocket is launched vertically upward from the edge of a cliff 80 ft off the ground at a speed of 96 ft/s. Its height above the ground is given by the function \(h(t)=-16 t^{2}+96 t+80\), where t represents time measured in seconds.
a. Assuming the rocket is launched at t = 0, what is an appropriate domain for h?
b. Graph h and determine the time at which the rocket reaches its highest point. What is the height at that time?
