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.

Question
## NASA Rocket Launch and Splashdown Time Calculation

NASA launches a rocket at \( t = 0 \) seconds. Its height, in meters above sea-level, as a function of time is given by \( h(t) = -4.9t^2 + 172t + 339 \).

### Problem 1: Splashdown Time

Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?

**Input Field**: 

- The rocket splashes down after **[________]** Preview seconds.

### Problem 2: Peak Height

How high above sea-level does the rocket get at its peak?

**Input Field**: 

- The rocket peaks at **[________]** Preview meters above sea-level.

In this educational exercise, students are required to determine the time at which the rocket reaches the ocean level and the peak height of the rocket during its flight. They need to solve for the values of \( t \) and \( h \) respectively, given the quadratic equation describing the rocket's height as a function of time.
