### Newbie. Hey!

I'm new here with a really nice freestyle.

I know everything about anything so ask me a question.

What is the air-speed velocity of an unladen swallow?knowitall wrote:I know everything about anything so ask me a question.

### Re: Newbie. Hey!

15 parsecs/sec

Next question please.

Next question please.

### Re: Newbie. Hey!

Is that an African or European swallow?

### Re: Newbie. Hey!

Do I have to handhold you through the entire answer?

It's either depending upon the wind velocity and weight of the bird.

### Re: Newbie. Hey!

You see if I gave you the answer I would only feed you for a day but if I forced you to think for yourself then I would feed you for a lifetime.jaunty75 wrote:Yes!knowitall wrote:Do I have to handhold you through the entire answer?

### Re: Newbie. Hey!

How does that go?..........give a man a fish and you will feed him for a day. Give him the internet and he will starve to death

Every forum has a know it all. I'm just being honest about it. So who am i replacing here?lkreykes wrote:wow, knowitall, you are pretty much arrogant. sorry butsounds pretty greedy. just saying...knowitall wrote:I know everything about anything

### Re: Newbie. Hey!

Your answer as shown is:

15 parsecs/sec

Please show your formula and

calculations used to arrive at that

Assuming that swallows travel in right angles and using the distance to the sun for relativity:KAH wrote:Your answer as shown is:

For a right triangle,

sinP = 1AU/d

where p is the parallax, 1 AU (149,600,000 km) is approximately the average distance from the Sun to Earth, and d is the average distance to the originating point of the swallow. Using small-angle approximations (valid when the angle is small compared to 1 radian),

sin x = x radians = x * 180/PI (degrees) = x * 180 * 3600/PI (arcseconds)

so the parallax, measured in arcseconds, is

p" = 1 AU / d * 180 * 3600/pi

If the parallax is 1", then the distance is

d = 1 AU * 180 * 3600/pi = 206,265 = 3.2616 ly = 1 parsec

From measureable data a swallow will travel an average 0.5 ft in 0.66 seconds and given that 1 parsec = 0.05 ft. Also assuming no friction then the average speed of a swallow is

(0.5 ft/ 0.66 sec) * (1 parsec/0.05 ft)= 15.15 parsecs / second

Class dismissed. Final exam will be next week.

### Re: Newbie. Hey!

Bit of a small mistake here:

sinP = 1AU/d

You obviously have the relationship of

AU / d mixed up. Since you are assuming the AU to be relatively constant and then dividing it by the flight distance

then you have the Cotangent function, not the Sine.

Sorry, minus two points already.
