h=-4.9 t + 121 t + 192 Assuming the rocket will splash down into the ocean, how long after launch does that occur? The rocket splashes down after seconds. How high above sea-level does the rocket get at its peak? The rocket peaks at meters above sea-level. Round your answers to the nearest whole number. Hint: Splashdown occurs at an x-intercept. The maximum height occurs at the vertex. h=-4.9 t + 121 t + 192 Assuming the rocket will splash down into the ocean, how long after launch does that occur? The rocket splashes down after seconds.
