NASA launches a rocket at T=0 seconds. Its height, in meters above sea-level, as a function of time is given by: h\left(t\right)=4.9t^{2}+250+283 . Round your answers to 1 decimal place. a. How many seconds does it take for the rocket to reach its maximum height? b. What is the maximum height in meters

We are given the height function for the rocket as:

\[
h(t) = 4.9t^2 + 250t + 283
\]

This is a quadratic equation of the form \( h(t) = at^2 + bt + c \), where:
- \(a = 4.9\),
- \(b = 250\), and
- \(c = 283\).

### a) Finding the time at which the rocket reaches its maximum height:

For a quadratic equation of the form \(h(t) = at^2 + bt + c\), the time \(t_{\text{max}}\) at which the maximum height occurs is given by the formula:

\[
t_{\text{max}} = \frac{-b}{2a}
\]

Substituting the values of \(a\) and \(b\):

\[
t_{\text{max}} = \frac{-250}{2 \times 4.9} = \frac{-250}{9.8}
\]

Let me calculate that.

The time at which the rocket reaches its maximum height is approximately \( -25.5 \) seconds, which doesn't make sense in the context of this problem. The negative time suggests we made a mistake interpreting the question. Upon closer review, the correct height function should be:

\[
h(t) = -4.9t^2 + 250t + 283
\]

This indicates a downward-opening parabola, and the correct formula will now be:

\[
t_{\text{max}} = \frac{-250}{2 \times (-4.9)} = \frac{250}{9.8}
\]

Let me calculate that again correctly.The time it takes for the rocket to reach its maximum height is approximately \( 25.5 \) seconds.

### b) Finding the maximum height:

To find the maximum height, substitute \( t = 25.5 \) into the height function \( h(t) = -4.9t^2 + 250t + 283 \).

Let me calculate that next.It seems like I can’t do more advanced data analysis right now. Please try again later.
