1. ## Just a few question

Hey bossman, I have been pondering some questions about this universe we live in and a few of them have stumped me. for instance: What is radiation that goes beyond the EM spectrum? If the light that is reflected into our eyes is from the past wouldn't that make finding intelligent life(regardless of whether or not you agree its out there) nearly impossible? And if we are currently living in a time after the big bang had cooled down for planets and stars to form wont the universe continue to cool down to an unlivable universal "ice age" that won't cease until another singularity occurs? If you can answer any of these for me that'd be greaaattt. If not whatever, half of life is questions that cant be answered.
2. ## Eureka

Hey just wondering if anyone has seen the show Eureka on syfy channel because if even a speck of what they say is even remotely possible than physics is even more of a favorite science of mine than before.
3. ## Car Crash Webquest

Dylan, Sarah, Joe 12/20/11 In order to find out if the SUV was speeding, we first had to find out the velocity of both the SUV and the wagon immediately following the collision. We found that the velocity of the SUV was 2.83 m/s and the wagon was 12.0 m/s. These values were found by using the kinematics equations to find Vi because we already had enough information to solve for the unknown in Vf^2=Vi^2+2ad. Then, we could find the momentum of the wagon and SUV immediately after the collision using p=mv. The momentum of the SUV was 8490 Kg x m/s and the wagon was 24000 Kg x m/s. With this information, we could figure out the momentum of the cars immediately before the collision. Obviously, the wagon was zero because it wasn’t moving. By using the momentum tables, we could solve for the velocity of the SUV which was 10.83m/s. Once we got that we could multiply that by the SUV’s mass (3,000 kg) in order to get the momentum before the collision, which turned out to be 32490 kg x m/s. Finally, we could find the speed of the SUV before the collision from the momentum table which was 10.83 m/s and the speed of the wagon was 0 m/s because again it wasn’t moving. Once we converted 10.83 m/s to km/h, we discovered that the Suv was going 39 kilometer per hour. The speed limit was 35 km/h, so the SUV was speeding.
4. ## Introducing Leekspinnah

Nice bro, both Science and Philosophy interest me as well and I can't wait to talk about both with you and others on this forum!
5. ## Say hello to Mammoth

didn't draw the avatar myself i just saw it and thought it was good
6. ## Say hello to Mammoth

Hello i am Mammoth, and some basic things about me is I like to draw and I hope to head on to college and eventually use drawing in what I do for the rest of my life. I decided to take regents Physics because physics has always been interesting to me, after all it is the entire world around us. Through Physics I hope to learn about and better understand the world around me and I can't wait for some of the projects this year. This year in physics I plan to become a better student all around, meaning better test grades, better involvement in the class and actually doing my homework. That's just a little bit about me and I look forward to using this site.
