Homework Statement A child slides down a slide with a 34 degree incline, and at the bottom her speed is precisely half what it would have been if the slide had been frictionless. Calculate the coefficient of kinetic friction between the slide and the child. Homework Equations \SigmaF...

I don't wish to argue with you. What does the title say? "Algebra road block". The physics and calculus part is easy. I know what to do. Thanks for the effort, but the standardized question format of this website should have prevented this problem. Next time stop thinking of how "stupid" I...

Thank you very much. That's all I wanted to know. Occasionally, I become blinded by my thoughts, and a simple thing is just overseen. I'm taking differential equations and physics for scientists and engineers right now, so I don't have a teacher willing to teach me "basics". Seeing an...

I was specific with my question. Don't reply unless you can answer my question. FYI, if I could get a teachers help don't you think I would have? Can anyone actually help me?

Sorry. This is where I am stuck... I don't know how to solve for 2 variables at once. I know I should have just as many equations as variables, but my algebra skills are horrible...

Algebra Road Block... Homework Statement The 100m dash can be run by the best sprinters in 10 seconds. A 66-kg sprinter accelerates uniformly for the first 45m to reach top speed, which he maintains for the remaining 55 meters. a) What is the avg horizontal component of force exerted on...

Thank you. It was hard to visualize for the very first time.

Homework Statement The summit of a mountain, 2450m above the base camp, is measured on a map to be 4580m horizontally from the camp in a direction 32.4 degrees west of north. What are the components of the displacement vector from camp to summit? What is its magnitude? Choose the x-axis...

I get it. So where do you stand on global warming? LOL. Just a joke. I'm kidding. ;)

I was just reading that the explosion of stars (supernova) could pressurize stardust to form new stars...

Amazing. It wouldn't be worth while to break one helium down to make what? 1 hydrogen? I see your point then... Any energy expended just leaves us with less and less..

Yea. I know. The more I read through it the more I understand...it's scary... SO with that theory there will not be a 2nd bang? If that is the case, then how did the first bang even form? Poetic. No? The "life and death" of the universe...

I don't buy it. Entropy has value to organisms and chemical reactions...I believe elements will reform...

But is it not true that new stars are formed? I don't buy it. Entropy has value to organisms and chemical reactions...I believe elements will reform...

Yet! LOL. You are totally right. It wasn't a breakthrough. :) Even in my own mind. Well, we need to find a way to put it to use! I mean, even as heat energy has it's advantages. We'll see it on automobiles soon. Pulleys that run solely on the influx of hot and cold air. The belt...
