When I joined I found this possibility interesting but asked myself if it is ever used.
But three days ago I asked: How is weight distributed when legs are astride? ? and got 0 answer.
As I needed the information I did some research and found a possible answer:
-I suppose that after 3 days I can answer my question,
I suppose that if I post it I cannot upvote it, but,
if it remains the only answer, what happens? I suppose I cannot accept my own answer
Technical Note: probably it's my poor eyesight, but at Physics. SE when a word is linked to an URL, it is terribly difficult for me to notice it. I keep swinging the mouse on every word to check if the colour changes. Is it possible to make it more visible, as it happens in other sites of SE, making it of a different colour before the mouse touches it? Even here at Meta it looks better
The only reservation I have is that your question is rather elementary
I discovered it is, the point is that there are always doubts, when physics is concerned, anyway we both answered such an elementary question Why is acceleration constant in this example? or such a silly one: Describing Objects in the First Dimension
Probably for you it is an exception, but, as I am more ignorant than a student, answering simple question is for me ordinary run of the mill: race between hare and tortoise, etc,,Two runners on two different tracks, etc. This last is really elementary, but it sparked of an interesting controversy nobody will ever settle. And what about this:Determining the decay constant for a damped wave, is it less elementary than mine?
Should I delete my question?, but I thought this practice is discouraged.
Personally I am content with my solution I do not need to post it for other members. If future viewers will have same proble, will post same question again. (btw: the horizontal friction it is not easy, unless you are an engineer). It seems that our average viewer is worried by spaghetti and meatballs and how you can run away fron your shadow!!!
