OK I have anothere quesstion about getting to th moon,sun, pluto,alpha centuri from the earth.?

Question

1. How fast in mph would it take you to get to the moon in 4 days if you ignore velocity needed to escape the earths atmosphere and if you ignore gravity and have infinite fuel.

2. How fast in mph would it take you to get to the sun in 228 days if you ignore velocity needed to escape the earths atmosphere and if you ignore gravity and have infinite fuel.

3. How fast in mph would it take you to get to Pluto in 9 years if you ignore velocity needed to escape the earths atmosphere and if you ignore gravity and have infinite fuel.

4. How fast in mph would it take you to get to Alpha Centuri in 30 years if you ignore velocity needed to escape the earths atmosphere and if you ignore gravity and have infinite fuel.

Answer 1

Your questions are simply arithmetic problems since you want to ignore all the real facts like gravity and so on.

Speed is distance divided by time. You give the time (4 days to the Moon for example). All you have to do is look up the distance to the object and divide. For example the Moon is about 240,000 miles away so the speed would be 240,000 miles / 4 days, which is 60,000 miles per day. There are 24 hours in a day, so 60,000 miles per day is 60,000 / 24 = 2,500 MPH.

The Sun is 93,000,000 miles away.

Pluto is 40 times as far away as the Sun, so multiply 93,000,000 by 40 to get the distance.

Alpha Centauri is about 271,400 times as far away as the Sun, so multiply 93,000,000 by 271,400 to get the distance.

You can do the arithmetic.

Answer 2

The solution method for each one of these questions is the same. Your assumptions (ignore gravity, atmosphere) would seem to simply be saying that you're assuming a constant velocity from start to finish. These then reduce to simple division problems (and some unit conversion, too).

The velocity, therefore, is simply the distance in miles divided by the time in hours. You can find the distance to these planetary bodies from your astronomy text or from an online resource, and you're given the time period for each question. In each case, convert the distance to miles, convert the time to hours, and divide.

Answer 3

each and every of the planets, aside from Earth, have been named after Greek and Roman gods and godesses. The call Earth is an English/German call which only ability the floor. It comes from the previous English words 'eor(th)e' and 'ertha'. In German that's 'erde'. The call Earth is a minimum of one thousand years previous.

Answer 4

to ignore,is either to know or to not know.Is a state of blinded heart,distraction path.The question is whom to ignore and whom not ? 60 mills forest is a soul.Th Moon ,Alpha Centauri,Sun don't know what once was lost.
