Juri is tugging her wagon behind her on the way to... wherever her wagon needs to go. The wagon repair shop. She has a trek ahead of her--five kilometers--and she's pulling with a force of 200 Newtons. If she's pulling at an angle of 35 degrees to the horizontal, what work will be exerted on the...
Correct me if I'm wrong, but What I've gathered is the general form of the wave equation is given as ψ = e^i(kx - ωt). And since this represents a wave, I related it to my past history of mathematics with sin and cos graphs when there were transformations, in the form of for example: y =...
I see that now, thanks!
I guess I don't even need the Energy equations at all to derive that k = p / ħ
I then guess one of my other curiosities was what is k = 2π/λ derived from, and how does it relate to the topic of Schrodinger's Equation and Wave Functions? Because that's the topic...
I began by taking E = mc^2 and E = hf , where h is Planck's constant, and then rewrote E as 1/2mv^2.
I rewrote f as c / λ, which made hf become h*c / λ. I then set this expression equal to the Kinetic Energy equation 1/2mv^2, which gave me:
1/2mv^2 = h*c / λ
I then replaced c on the...
I appreciate your reply. I think I follow this. I understand it in plain English as you explained it. But to translate that to mathematical equivalents such as 2M/3L and 4M/3L is the part that I'm struggling with.
To answer your question, yes. I/m definitely unfamiliar with mass density. The class I'm taking is an archived Physics course with Calculus. I'm very well versed on Calculus and everything math related. But I always struggled with Physics. I passed it back when I took a Physics w/...
Well the wording of the problem had me confused. The λ1 "along the left half" sounds to me that you'd cut the stick in half. And the left piece would have the λ1 spot wherever 2M/3L would be calculated. And the same for the right half piece and 4M/3L.
Is that the correct way to look...
Homework Statement
Find the Center of Mass locations of a thin stick of mass M and length L, whose left ends are at x=0.
The stick has uniform mass density λ1 = 2M/3L along the left half, and has uniform mass density λ2 = 4M/3L along the right half.

I know that this is...
In this course, we haven't gotten to relativistic calculations at all yet. The topic we're on is conservation of momentum, impulse, force and center of mass.
Hello. I recently began this problem, but the site I'm working this problem on isn't showing me whether the answer is correct or not. Can someone please check my work and just verify that it's correct or state if it isn't and why?

omg... I feel so dumb sometimes.
The (halfway) I see now meant HALFWAY BETWEEN 0L and 3L in the y-direction which is 1.5L. Which I now see is equivalent to 9mL /6m.
The wording of these things always gets me confused. Thanks for helping to clear this up for me.
Homework Statement
Three spheres are placed around a coordinate grid: one of mass m at the bottom-left, one of mass 3m a distance of 3L above the first, and one of mass 2m a distance of 4L to the right of the first.
4 points between these three spheres are labeled: A near (1.3L, 1.5L), B...
