Fermi Questions C

And we return!

How fast, in decimeters per hour squared, would a 2017 Volkswagen Beetle, which is currently orbiting the Earth at 700 km altitude, have to be accelerating in order to use as much power as the sun emits?

From what I can tell, this is definitely from the more difficult end. Easier ones involve much simpler premises and conditions, i.e. what is the distance, in megaparsecs, that a snail travels in the amount of time it takes Pluto to make a full revolution around the sun or something like that.

Re: Fermi Questions C

C'mon (Fox reference from SSBM weeb I know clarification)
Distance is approx let's say 10^25 m (Adi don't kill me I don't know Astro at all). Each quarter is let's say 1 mm thick, and approximately 6 grams. That's 10^28 quarters times 6 would round it up to 29 as a fermi answer.

I'm bad at math let's not try this again

attempt

oops I messed up not rly

New question:
How many paper airplanes woudm it take to equal the mass of one airplane? (use Boeing 777 as an example)

EDIT: raleway posted before me but didn't put a solution or anything so I'll leave my post here for solution plus next question
EDIT 2: spelling

Re: Fermi Questions C

For Neil (Lemme not fail again at units)

Assume one plane is like 1 million pounds. I read on a study of paper that 100 sheets of standard A4 paper weigh exactly 1 pound... so the fermi answer would be 8?

Re: Fermi Questions C

How many times would a violet light (assume perfect light) wrap around the universe if it traveled for Googleplex to the Googleplex lunar months?

Re: Fermi Questions C

If I am interpreting this properly, you want the distance light travels in Googolplex^Googolplex lunar months, and how many times that would wrap around an arbitrary equator of the visible universe.

If that's the case, I really can't see how you'd express that as a Fermi answer, unless you accept 10^(100+10^100)-12 .

More likely than not though I'm just reading this problem wrong.

I'll admit, I had to look up the radius of the observable universe. I got:
this

Not 100% sure I did that right.

A horse walks into a bar. How fast would he have to be walking into the bar in order to have the equivalent amount of (kinetic) energy as 10 million chickens crossing the road at normal chicken speed?

I don't think that's right, but whatever.

Supposing pencils can be made out of any wood (not just cedar), if I cut down the entire Amazon Rain Forest and used the wood to solely manufacture pencils, and used them to draw one, straight, unbroken line, how long would the line be, in Angstroms?

Re: Fermi Questions C

I doubt I could ever solve this without info, so I'll post the solution for anyone who wants to check their work:
