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+121t

Alenkasestr [34]

NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by

$h(t)=-4.9t^2+121t+283$

The sea level is represented by h = 0, therefore, to find the corresponding time when h splashes into the ocean we have to solve for t the following equation:

$h(t)=0\implies-4.9t^2+121t+283=0$

Using the quadratic formula, the solution for our problem is

$\begin{gathered} t=\frac{-(121)\pm\sqrt{(121)^2-4(-4.9)(283)}}{2(-4.9)} \\ =\frac{121\pm142.083778...}{9.8} \\ =\frac{121+142.083778...}{9.8} \\ =26.8452834694... \end{gathered}$

The rocket splashes after 26.845 seconds.

The maximum of this function happens at the root of the derivative. Differentiating our function, we have

$h^{\prime}(t)=-9.8t+121$

The root is

$-9.8t+121=0\implies t=\frac{121}{9.8}=12.347$

Then, the maximum height is

$h(12.347)=1029.99$

1029.99 meters above sea level.

The partial pressure of carbon dioxide in a mixture is 0.31 atm.

juin [17]

Answer:

$P_{Co2}= X_{Co2} P_{tot}$

Where $P_{tot}$ represent the total pressure and $X_{Co2}$ the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

$P_{tot}= \frac{P_{Co2}}{X_{Co2}}$

And replacing we got:

$P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm$

Step-by-step explanation:

For this case the partial presure of carbon dioxide is given by:

$P_{Co2}= X_{Co2} P_{tot}$

Where $P_{tot}$ represent the total pressure and $x_{Co2}$ the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

$P_{tot}= \frac{P_{Co2}}{X_{Co2}}$

And replacing we got:

$P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm$
