Oh man, you're right! Thank you.

Homework Statement A small block with mass m is placed inside an inverted cone that is rotating about a vertical axis such that the time for one revolution of the cone is T. The walls of the cone make an angle β with the vertical. The coefficient of static friction between the block and the...

I've noticed a lot of talk about music and movies and such, but no one really has mentioned the fact that books can be pirated too. It's very easy to find PDFs, and even instructional videos on these sites. I paid over $200 dollars for a calculus book that was replaced by an updated edition the...

AWWW... I have it now. I was adding R to the final result instead of R\sqrt{5}/3. Thank you for all you help and patience.

Wow thank you! With all the trouble I'm having in solving T, I would have never thought of getting rid of it. I am a little confused in the calculation though. Now I'm getting d = 1.44. When you found that R/sin\alpha = 1.342 R, you used the angle 48.2 (the angle from the vertical to the initial...

Ok... I've done it four times now. Each time getting a different answer. lol Does d = R(1.66) sound reasonable to you?

Thank you very much for responding ehild... Two equations? Are you talking about the constant acceleration equation I provided? One in terms of X, and the other in terms of Y? and Is the angle you're referring to, 41.8 making... Xi = r\sqrt{5}/3 Yi = 2r/3 Xf = d yf = 0...

Conservation of Energy- A Skier on a Snowball Homework Statement A skier of mass "m" starts at the top of a very large frictionless hemispherical snowball of radius "r" with a very small initial speed and skis straight down the side. Treat the skier as a point particle. a) At what angle...
