A m=1.08E3 kg satellite orbits at radius Rs=2.58*107 m about the center of a planet of mass M with a speed of v=3,943 m/s. (Recall U=-GMm/ Rs. So the gravitational potential energy is zero at infinity. G=6.67*10 -11 N*m2/kg2.)

a) What is the value of the mass M of the planet?

b) What is the total mechanical energy (K+U) of the satellite?

A uniform circular disk (merry-go-round) of radius R=1.60 m and mass M=37.0 kg freely rotates about a vertical axis, which is perpendicular to the ground, with initial angular velocity ωi=2.80 rad/s. A cat of mass m=5.30 kg, climbing in a tree, which hangs over the disk, falls straight down onto the edge of the disk and rides on it.

a) What is the magnitude of the angular velocity of the cat/disk system after the cat has landed?

b) The cat decides to walk inward and sits down R/2 m from the center. What is now the magnitude of the angular velocity of the cat/disk system?

What year was it?

What was it?

Some would think so! What do you think? Maybe we are just so intelligent that people assume we are the same person!!! lol inside joke!!!

"Forever you will be hollow"---Project 86

Making 1 out of 2 Rules!!!!

What is the farthest back anyone has come from to win(1) Who was it (2) what year was it (3) how many laps did he lead (4) and who was on the pole (5)

Kissing those Bricks Rules!!!!

My friend definately isn't after he jumped on Ricky Rudd's car a while back!!! If you are, today is your lucky day!!! :)

I got a message from GameStop last night that the game would be in around noon central time!!!! Wooo Hooo!!!! We don't have to wait any longer!!! Well I do, I'll have to wait to play it tomorrow night, but hey that's alright with me!!!!

NASCAR 08 RULES!!!!

1. Who won the pole for the very first Daytona 500!

2. Who won the race!

3. Who came in second!

Winning the Daytona 500 Rules!!!!

Name it and guess the brand of shirt I'm wearing today and you get 10 points.

---It's not a Gordon shirt, I'm at work lol!

Racin old school Rules!!!!

All this talk about who rules, but who drools?

Gordon Rules!!! Hugh Hefner Drools!

Tell me who or what you think "Rules" the most!!!!

Anyone but David g gets best answer!!! I'm not serious!! Just messin with ya man!!!

You all Rule!!!!

Think you know? :)

At the bottom of the page it has a question of whether suspended crew chiefs should be allowed to communicate with their teams and it has a picture of Steve Letarte next to the question. I swear every single pole NASCAR.com presents on their website I can almost guess what answer is most popular and by what percentage. Well I wasn't wrong today and I would love to go back in time and have them put a picture of Tony Eury Jr and see what the results would have been. as it stands the percentage is Yes 28% and No 72%. What do you think the results would have been had the picture not been a Hendrick crew chief?

Is known for having 3 different straightaways and 3 different corners with different radii?

Easy one!

I you could design a track and each corner had to be different, how many corners would you put in? What corners from other tracks would you include in your track? Your shape doesn't necessarily have to be oval, your track can be whatever you want!

Most creative track wins!

Give me your top three picks, if you say your fav. driver then give me another one, and where are you from? Just like to know where all the people are! As a bonus I'll give 10 points to the person who can guess where I'm from! It's in the U.S. and innapropriate answers will be dealt with accordingly. Thanks!

Alright everybody it's Mr. Juanderful's ( I hate that nickname) week to shine. Will he shine or will he become overaggresive? Is Scott Pruett racing? Will he get the ultimate revenge and give Montoya a little nudge? It would hurt Montoya way more than the bump hurt Pruett at the busch race in Mexico. I'm sure Pruett has a lot more class than Montoya, but ya know, it's only fair!!! They call those "one of those racin' deals" :)
