The exhaust from a hydrogen-oxygen rocket goes about 4.4km/s. If I want to reach a velocity of 22km/s (in a single stage), what is the minimum possible mass of the rocket compared to the final mass?

Question 2 10 pts 400 300 M initial / M final 200 100 N 4 5 6 Av/ve From 'The Rocket Equation, Part 1 ' The exhaust from a hydrogen-oxygen rocket goes about 4.4km/s. If I want to reach a velocity of 22km/s (in a single stage), what is the minimum possible mass of the rocket compared to the final mass? 6 times its final mass 20 times its final mass. 150 times its final mass. 1000 times its final mass.Question 4 40 pts For this question, you will probably want to use this website allows one to explore the universe E> - from the very small to the very large.

It took the Apollo astronauts 3 days to reach the moon - it is the fastest that humans have ever traveled (their fastest was 11km/s, but they were on a 'minimum energy' orbit that slowed dramatically as they got closer to the moon and traveled more distance than a straight line, and were 1km/s or so by the time they got to the moon, so the average was much slower). Given the approximate average speed to the moon (straight line distance of roughly 385000km , divided by the time), match how long it would take to reach the following objects at this speed (you can do this by Mg, and using this website E), or by direct calculation if you look up the numbers). the Sun [Choose ] V Sedna [Choose ] V Proxima Centauri [Choose] V Neptune [Choose] V Question 3 10 pts The gure above is an exponential function of the form Mnitial/Mfinal 0c Emma/vans\": For a function of this type, what happens to the initial to nal mass ratio as the desired nal velocity increases? Q It tends towards low values; high speed travel with conventional rockets is in principle straightforward. Q It becomes constant; high speed travel with conventional rockets is in principle reasonably challenging. Q It tends towards shockingly high values; high speed travel with conventional rockets is in principle extremely challenging. Question 5 30 pts What are some of the reflections that you have on the scale of the solar system and the galaxy, and the timescales characteristic of this type of long-distance travel?

Q) As exhaust goes out the back, an equal and opposite force pushes the rocket forwards.
