NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by h(t) = – 4.9t² + 172t + 339. Assuming that the rocket will splash down into the ocean, at what time does splashdown occur? The rocket splashes down after Preview seconds. How high above sea-level does the rocket get at its peak? The rocket peaks at Preview meters above sea-level.
