Thanks for clarifying. I'll have to rework this, as I thought the trick was the track. Based on that assumption I was originally going to say
v1 = v2 = 0, the track is a moving walkway so you don't have to run at all
complete with work to mathematically back up that claim. But I guess that's not the solution you wanted.
hahaha XDDD
lemme clarify again, the track is a super-normal-non-moving-straight track :)
Now, let me ask this. Why would I run if I am imagining everything?
hmmm... lemme delete the word...
you guys are more creative then me :)
this is not a word game :(
the tricky part is more on the scientific side!
