This is of my own interest/ practice. Homework Statement A thin rod (of width zero, but not uniform) is pivoted freely at one end about the horizontal z axis , being free to swing in the xy plane (x horizontal, y vertically down). Its mass is m and its CM is a distance a from the pivot. The...

So... as hella confusing as that question is worded, I'm going to assume a thing or two... Since the ball is in the plane of the disk, I'm going to assume that it is shot in the direction (or counter to it -) of the spin. My response to this is to calculate the angular momentum of the ball at...

In this problem, it's more about the Work done to the train to get it to come to a halt. First they give you the train's mass and velocity. (Remember: Kinetic Energy http://www.sciweavers.org/upload/Tex2Img_1418868535/render.png ) If we look at the the energy of the system, it goes to...

Hmmm, I hope to be able to take my knowledge of physics and apply it. (to what, still unsure). But in the mean time, I'll be learning as much as I can and giving back to the physicists-to-be (especially at PF). ;)

*walks in* *takes off Sunglasses* ..Sup (Because just saying hi is not enough.) I'm a student a Johns Hopkins and I'm double majoring in Physics and Mechanical Engineering. And NO, I am not a doctor.
