I'll be at LSU; I was offered the position on March 18. Anyone else?

I'll be at LSU for the CCT REU.

We know m \frac{v^2}{r} = \frac{k e^2}{r^2} and m v r = n \hbar (the quantized momentum of the particle) so \frac{m v r}{r^2}v = \frac{k e^2}{r^2}. That should give you enough info to solve for the electron's speed!

Got an offer from Stanford Research Institute's PSD REU program!

I figured it out. Found something on Wikipedia. I'll let other people look at it for a day before I post what I found.

This is a tough question. I'd like to know if anybody can find a good solution. It isn't required for any of my classes, but I'd like to see a theoretical result. It seems like it should be a simple projectile motion problem, but it's not that easy. Let's say there's a building x1 meters away...

First, make sure you convert km/hr to m/s. 4 km/hr = ~ 1.1 m/s 2.8 km/hr = ~ .78 m/s We know that friend 1 is going to travel fast from A to B on the first part of the trip because he has a current behind him. His velocity of rowing will just be added with the velocity of the water. When he...
