Question

1. The distances between objects in the universe are huge! Use the website to fill out the chart

below. Let's say you were to go the speed of a car (65 mi/h), a jet going the speed of sound (760
mi/h), a bullet (1,500 mi/h), the Voyager 1 Space Probe (38,000 mi/h) and an imaginary space
ship that goes 99.8% the speed of light (186,000 mi/sec). How long would it take to get to the
following places?
Car (65 mi/h)
Destination
Earth's Moon
Mars

3. What is the difference between a manned and unmanned mission?
2. It took the Apollo 11 astronauts 4 days and 6 hours to get to the Moon. What object's speed
from the above were the Apollo 11 astronauts traveling the closest to?
Imaginary
Space Ship
(186,000
mi/sec
4. Why do you think we haven't sent a manned mission to another planet?
5. Why do you think we haven't sent an unmanned mission to another star or galaxy?

Answer 1

The distances between objects in the universe are vast and require high speeds to reach them within a reasonable time frame. The speeds provided would take different lengths of time to reach destinations within our solar system and the universe. The Apollo 11 astronauts were traveling closest to the speed of a bullet.

Step-by-step explanation:

1. The distances between objects in the universe are incredibly vast, which requires very high speeds to travel to them within a reasonable time frame. Let's consider the speeds provided and calculate how long it would take to reach various destinations:
