I dunno what you are trying to work out

Observer 5 feet

Fine I'll change it

Observer 5 feet. 15000 feet..5 feet gone

Ok but this is the information that was given, yea?

Thats with 20/20 vision

🤔

The object would be gone from view at three miles away

We good so far?

Thats what it seems to be when tested at the beach

Ok I'll keep going then

At about 3 miles 5 foot objects are gone

K keep goin. Dont forget to read James gibson

Gnite

Ok just a sec I'm doing the math

Tired nite

This is what the angle would be using the height of the observer and the distance of three miles

Which part ?

1 inch off the ground or 5 feet up?

6 feet?

I'm tired gotta goto sleep

The angle that was labeled in the last pic

Ugh whatever ok

What height did you use?

This is the distance the object would disappear using 0.02 as the angle and 6ft as the height of the observer

I used 6 ft for both

Feel free to check the math

It's simple geometry

Cool.thanks ill look at it

Ok tell me what you think when you're done

So what r u saying?

According to the information provided, objects of the size specified would vanish fully at 299.96 feet instead of 3 miles

You must of done something wrong

You're welcome to find where I messed up

Think about what you are saying

I did

5 foot object doesnt disappear at 300 feet

It does at 3 miles

Now you're catching on
