NASA launches a rocket at t O seconds. Its height, in meters above sea-level, as a function of time is given by h(t) – 4.9t? + 163t + 227. - Assuming that the rocket will splash down into the ocean, at what time does splashdown 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.

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) = – 4.9t + 325t + 346. Assuming that the rocket will splash down into the ocean, at what time does splashdown occur? (Round to the nearest tenth.) The rocket splashes down after seconds. How high above sea-level does the rocket get at its peak? (Round to the nearest tenth.) The rocket peaks at meters above sea-level.

The height of a projectile t seconds after launch is given by the following function: h(t) = −9.8t² + 350t +3. How long will it be in flight? Round to four decimal places. A
