And you refuse to admit that I do understand the concept by what I wrote here.
Anyways, go right ahead.
Post a question.

Could have. And maybe magic pixie dust came by to make all the problems go away.
Gogo magic pixie dust.

And what did I write in the thread here?
Did I not *just* write that the Force is three times greater?
Yes, I put coefficient several months ago where I should have put the force. I was more concerned that the math was right as I was trying to commentate out the equations.

I wrote right here in the thread, where you accused me of not understanding the concepts.
I wrote it out right here that the FORCE of friction is three times higher, with both weights combined.
Why are you arguing against what I wrote months ago? I was thinking out loud, trying to answer the question before I had to head out the door.
I figured had I left the question when I had more time, that you'd accuse me of running away. Oh, as you did anyways.
Okay, let's explore that. You made this post in a hurry:
Spoiler:Ok.
Block exerts a force = F= ma which basically acts to change the mass of the overall system from M to 3M.
So the coefficient of static friction now is 3M(mu) as opposed to M(mu), meaning that the Frictional force is 3x the original frictional force.
F= Fm - Ff =
v= S
Ek = 1/2 mS^2.
Ef = Eo
1/2 mS^2 = 1/2 3mT^2
sqrt(S^2/2m) = T
so that will give you the speed of the combined blocks.
For question one.
Vi = 0
Vf = sqrt(S^2/2m)
vf= vi + a*t
sqrt(S^2/2m) = g*t
t = sqrt(S^2/2)/g
Then 18 minutes later you made this post:
Spoiler:HC, maybe you can answer a question that Kuci got wrong.
Betelgeuse is a star located 640 ly away from the earth.
RA is 5h 55m
Dec is +7 deg 24'
What are the coordinates of betelgeuse in cartesian coordinates, assuming the Sun is 0/0/0
Where did you go that allowed you to be there and back again in 18 minutes?
Then 28 minutes later, this:
Spoiler:That's how I solved for the velocity. Energy is conserved. You can use momentum too.
The rest is kinamatics equation. I know the final speed, and the initial speed, the acceleration and from that I can find the time.
Yeah, you were really in a hurry to get out the door. That's why you were still around 46+ minutes after you made that post!

Clearly your understandment of the topic is much less than stellar.
As opposed to the years of work that I actually did do and did quite well?
Are you willing to admit you might just be wrong about me?
If not, put up another question. You've got 3 and a half hours now.Scouse Git (2) La Fayette Adam Smith Solomwi and Loinburger will not be forgotten.

You made several statements which just contradict your claim that you are great at physics. I don't really care if you are, but if you claim something and then posting evidence otherwise, then don't get mad if people call you on it.
And after you make mistakes this basic on something you claim to know, you ask us to believe your take on something over people who actually know about it?Indifference is Bliss

You would have still been wrong if you had put force.
"Frictional force is proportional to the weight of the objects and the coefficient of friction"
I alrady mentioned this, and explained why. This is why people dislike you, you ignore and twist others' arguments, and change yours.
You made several statements which just contradict your claim that you are great at physics.
All I'm asking is that you respect the work that I have done. That's it.
I don't really care if you are
You obviously do care because you take pleasure in pointing out where I've made a mistake, because it makes Nestor look better.
if you claim something and then posting evidence otherwise, then don't get mad if people call you on it.
would you like that very much?
I think personally, you are being very two faced here. On one hand you tell us you don't care, but on the other hand you think it's ok.
And after you make mistakes this basic on something you claim to know, you ask us to believe your take on something over people who actually know about it?
I asked you didn't answer. Do you believe you have been fair to me?Scouse Git (2) La Fayette Adam Smith Solomwi and Loinburger will not be forgotten.

Physics problem for ben, since he asked. Let's watch him get pwned:
The pendulum bob and the box are released from rest in the position shown in the diagram below. The contact between the box and the horizontal surface has negligble friction. As luck would have it, the mass of the pendulum bob and the box are equal ( both masses = M ).
(attached image here)
a) Find expressions for the velocities of the box and the bob ( with respect to the fixed horizontal surface) at the instant the bob reaches it lowest point.
b) Find an expression for the tension in the string when the bob reaches its lowest point.
c) Find an expression for the acceleration of the center of mass of the system at the instant the bob reaches its lowest point.
d) Find an expression for the upward contact force on the box from the horizontal surface at the instant the bob reaches its lowest point.
If there is no sound in space, how come you can hear the lasers?
