Oh! The mysterious intrigue! Dun Dun Dun...

Asimov is on my list of authors to start familiarizing myself with. I am acquainted with Asimov's laws of robotics of course (they really push the ethics stuff in bioengineering...), but have yet to actually read any of his novels. I have not read Childhood's End. I really need to start brushing...

The holidays are upon us. With the holiday's comes time off work and school for many. What books are you reading during your spare time? Do you Have any Favorite holiday reads? Perhaps some guilty favorites? Currently I am working on four novels: 1. The Elegant Universe by Brian Greene 2. Anna...

I"m still not sure that I understand that. To clarify, I'll try to break down my method a bit more. Perhaps that will help show more thoroughly where exactly my understanding is flawed. To start, we know that WTOT = ΔKE + ΔU WTOT = KEf - KEi + Uf - Ui Because the truck goes from moving to...

Update: I solved the problem without incorporating the potential energy and the solution was correct. My answer came out to be .12km. However, I still don't fully understand why potential energy is not incorporated.

I live near Phoenix, Arizona. The gas station was in Phoenix. I had to drive a bit to get there too, but the savings were worth it. It cost me less than 30 dollars to fill up my tank when it normally costs me about $50...

...Christmas is just around the corner... : ). Hopefully, a new desktop is in order. Until then, I'll just have to stick stuff under my laptop to prevent it from wobbling.

Semi random: I just filled up my gas tank for $1.99 a gallon. That's insane. But pleasant at the same time.

Cool, Thanks! In the mean time I'll keep trying to work on it. I think the problem lies in the fact that I'm using potential energy, Uf. I don't think I am supposed to incorporate it, based on similar examples in my textbook. However, I also don't understand why I wouldn't incorporate it either.

I've got two problems that I can think of right now: 1. I didn't have a laptop desk for my new laptop. So I solved this first world problem by using my old laptop as a laptop desk. 2. My new laptop does not sit flat on the desk. It is raised slightly on the left side. And it makes it very...

Homework Statement Truck brakes can fail if they get too hot. In some mountainous areas, ramps of loose gravel are constructed to stop runaway trucks that have lost their brakes. The combination of a slight upward slope and a large coefficient of rolling friction as the truck tires sink into...

Okay, I re-solved the problem and got the correct answer. My method seemed to be correct. However, when I initially solved the problem, i did not account for the direction of the headwind (going against Sam). Because of this, I was getting an incorrect answer. Re-solved, my solution looked more...

Hi, I am new to this website! I'm learning how to use it to the best of my ability so please bear with me! I am excited to use these forums! They seem to be filled with wonderful information!

Sam, whose mass is 75kg, starts down a 50-m-high, 20 degree frictionless slope. A strong headwind exerts a horizontal force of 200N on him as he skies. Use work and energy to find Sam's speed at the bottom. Hi! I'm new to posting on this website but thought I'd give it a go! I would really...
