yzguy15 said:So you have block moving at velocity Vo along a track with kinetic friction constant u and initial acceleraction Ao. The mass passes through a frictionless "loop-the-loop" (think Six Flags rides) of radius R, and exits the loop with velocity V1. The block travels on the track for Xmeters until it hits a spring with spring constant K and goes back towards the loop. What is the velocity of the block when it is at the top of the loop the second time.
JMD said:Eric. there are a few things I'd need to answer that essay question. First, is the block made out of any kind of magic material with strange properties? Because that can throw everything off. Second, is anybody riding on the block, like a really fat broad? Because even though it might not make any difference to the answer, a thing like that can really be disgusting. Finally, where can I buy a frictionless loop like this, just in case I ever need one? See? They never tell you the really important information. Well, good luck anyway. Catch you another time.

evenslower said:I'm calling BS. You're actually in the library screwing around on DRN.
I just call em like I see em man. Good luck with the Physics.
JMD said:Yeah, that was our crew. I have the big white van and open trailer. Sorry we missed each other. Maybe next time. I'll probably be there again Saturday, unless I hit the Kiamichis.
