    Momentum of a particle.

    Here's a question from my workbook that I can't seem to figure out. A proton (mass = 1.6 x 10^27 kg) moves with a speed of 6 Mm/s. Upon colliding elastically with a stationary particle of unknown mass, the proton rebounds on its own path with a speed of 3.6 Mm/s. Find the mass of the unknown...

    I didn't mean that would give you a formula, but if you had a set of data, you could find the regression by plotting x, log y. It's not the answer but it's a way to get it.

    No Sound Coming From My Computer

    My motherboard's sound card is 6.1. My speakers are 5.1. Is that why my sound doesn't work when it's hooked up to the mobo? Does 6.1 not work with 5.1?

    Studying statistics - career options?

    A lot of statisticians work for businesses and predict future product sales/business growth. They also do surveys in the best interest of whatever the company is doing. I'm in a Stat's class, and I hate it. It's not challenging, just very, very dull.

    Schools Do you guys work while attending University?

    If you do work, don't get a job that will wear you out. I work 24 hours a week, which isn't a lot but I'm a lifeguard. Lifeguarding wears me out and I get home to do some homework and I'm too tired to do it. Not a good situation.

    As I don't agree with you entropy, it does prove a good point. There wasn't a best in the last generation of consoles (XBOX, PS2, and Gamecube), and there won't be in the next generation. Consoles aren't measured by their power, but the games on it. Different strokes for different folks.
