Math Problem Statement
Solution
The problem you're working with involves the function , which gives the height of a rocket over time.
Part 1: Splashdown Time
You correctly identified that the splashdown occurs at seconds. This was likely found by solving , which represents the height being zero (the point when the rocket hits the ocean).
Part 2: Maximum Height
It seems there was an error in your calculation for the maximum height. To find the time at which the rocket reaches its peak, you need to calculate the vertex of the parabola. For a quadratic function of the form , the time at which the peak occurs is given by:
For :
Now, calculate the peak time:
At seconds, the rocket reaches its maximum height. To find the height at this time, substitute into the original equation for :
So, the correct maximum height is approximately 648.95 meters.
