Yeah...that is why I'm quite confused. This isn't for physics either, this is "introductory" homework for strength of materials...

Homework Statement *See Attachment* The problem states to find "y" which I'm assuming is the change in distance from the original point marked "y". Homework Equations Hooke's Law The Attempt at a Solution I'm pretty sure the change in Y is -0.1in P=-ky y=p/-k y=-0.1...

Thanks for the help, I ended up re-working the first part with a friend and found out a more precise answer. Also, thanks for clarifying the last part, I simply did not understand the question and your explanation, well, explained it :)

A ski jumper starts with a horizontal take off velocity of Vo=20.0m/s and lands on a hill inclined at 30 degrees. (Note says to use a coordinate system that is not horizontal and vertical, so I rotated the coordinate system to make the ski jumper "take off" at Vo at the angle of 30 degrees. Thus...
