Question 1187327: NASA launches a rocket at t=0seconds. Its height, in meters above sea-level, as a function of time is given by h(t)= − 4.9t^2 + 229t + 122.

Assuming that the rocket will splash down into the ocean, at what time does splashdown occur? For intermediate work, keep at least five decimal places. For the final answer, round to the nearest hundredth.

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.
