Homework Help - October 2006

In my lab, I have to calculate the initial velocities of different trials for a ball rolling off a ramp. I had thought that the initial velocity would be zero but my teacher said that that's not it. So I decided to use t=0 and plug it into
x=x0+v0*t+(1/2)*a*t^2 but that gives me an intial velocity of zero too. So yeah, i need help.
Oh yeah, my range for the first trial, the distance the ball traveled, was 75cm.

Okay, maybe I should explain myself a little more.

My mom has been in and out of the hospital. My health has been going up and down. I just found out I was adopted. I've been breakingdown since my dad died. My weight has shot up so much I'm shocked my face hasn't even gotten a double chin yet. I have no support for what I do (I play the flute, piccolo, tenor sax, oboe, and clarient), and on top of all that I have saturday music school and religous ed., both in which I've worked so hard to get into. I have the same classes everyday, which means I have 9 hw assignments everyday and most assit of pages of essays. I wake up at 4:30 in the morning and don't get home until 5:30-7:00pm in the evening. I've cut French 1 and Music Theory because I needed to cry before the thought of suicide cam to mind. I need help and I know it but I have no one to go to. Freinds and boys are the last thing on my mind, so don't even mention them. WHAT SHOULD I DO!!!

I can do the base case and formulate the induction hypothesis (of course), but I'm not sure exactly how to prove this one. Inequalities give me a hard time. Please prove this as an example for me if you can. Thanks

A hard magnetic disk has two surfaces. The storage area on each surface has an inner radius of 1 cm and an outer radius of 5 cm. Each track holds the same number of bits, even though each differs in size from every other. The maximum storage density of the media is 10,000 bits/cm. The spacing between corresponding points on adjacent tracks is .1 mm, which includes the intertrack gap. Assume that the intersector gaps are negligible and that a track exists on each edge of the storage area. a.What is the maximum number of bits that can be stored on the disk? b.What is the data transfer rate from the disk to the head in bits per second at a rotational speed of 3600 RPM

ok we will have a Trial Presentation next week about Andrew Jackson.

I found some evidence that proved that he's the worst president for:
1. Vetoing the bank
2.Indian removal (I got this)
3.Trail of Tears (oh man! He sucks!)

but I was having a hard time to understand why he thinks that the Bank was unconstitutional? I kept on reading my book "The American Pageant" but it didn't explain deeply.

Also, can someone gave me (even a little bit) a counter-arguements about the 2nd Bank...I mean, should he really veto the Bank? (I know that the Constitution didn't mention the Bank but it was established by elastic clause)
