First off I just want someone to check and see if I got the right answer because I have no way of telling if it is the right answer or not. I am pretty sure I have the right answer but I have no way of checking.
1. Homework Statement
A spring with a stiffness ks and relaxed length L0 stands...
OHHH. So the force exerted from block two to block one is equal to the 7 masses of the blocks just sitting there * acceleration. And then the force from the last block only has one block to push against so its just m*a. My logic was just really bad on this problem haha thank you very much.
Yeah I tried that... but I don't think I am doing it correctly haha.
The blocks are lying on the table and he is exerting a horizontal force on block 1 causing all of them to move.
They way I thought of doing a freebody diagram is that the forces on 1 is the force from book 2 and Tom. Then on...
Homework Statement
Tom now pushes eight identical blocks on the horizontal and frictionless table (he’s compulsive). The force that block 1 exerts on block 2 is F12; the force that block 7 exerts on block 8 is F78. What is the ratio F12/ F78?
Homework Equations
F=ma
Δp = FnetΔt

Okay so I was wrong on b10 and a1 haha. I was looking at it wrong I was thinking it was saying all forces are either parallel or perpendicular to the momentum but what it is saying is all the component vectors can be split into those two pairs which makes sense to me. Really you don't have too...
Homework Statement
There are two parts to this question...
a)Which of the following are correct representations of The Momentum Principle? (assuming a small-enough Δt whenever it shows up)
1) \frac{Δ\vec{p}}{Δt} = \vec{F}|| + \vec{F}⊥
2) For every action there is an equal and opposite...
Oh okay. So it is just giving the points on the circle using Euler's formula. That's pretty cool. And if there is an infinite number of points it just gives you a circle since every point is filled. Thank you very much.
Homework Statement
For the series x^n - x^(n-1) - x^(n-2) ... - x^(0) the roots seem to be x = 2 and the circle around the complex plane with radius i or 1 I'm not sure how you would say it as n approaches infinity. Here's an image of the roots where n = 15...
Thank you for welcoming me. :) Ok, so I have to take the "partial" integral of the metric with respect to one variable, treating the others as constants. Correct? And I don't need the arc length between say the moon and the Earth if I know the radius. And I have to check my notes on the world...
Homework Statement
I have been trying to understand the actual applications and mathematics behind Einstein's Field Equations. I have watched a two hour long lecture on how they were derived and have pretty much understood it, however I still don't know how to actually "use" Einstein's Field...
