I am just a man who has an insatiable desire for knowledge.

"For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]."~ Philippians 4:8

comment Tensions And Pulleys With Masses
Oh, yes...The pulley would definitely have more rotational inertia, and that would diminish the amount of force transmitted, right?

What is effective mass, and what is c.g.?

comment Calculating Moment Of Inertia
Oh, so basically your process involves reconstituting the door by squishing the height, and uniformly concentrating the mass over the width?

comment Calculating Moment Of Inertia
So, there isn't really any intuitive way of seeing that the height isn't required?

comment Calculating Moment Of Inertia
Why is the height not needed, though?

comment Finding Constant Angular Acceleration
Thank you very much! I completely forgot about the rotational kinematic equations, until you had refreshed my mind.

@leongz Well, how would I find the time interval during which the centrifuge slows down?

Is this outwards force due to rotation perhaps the centrifugal force?

comment Does Earth's Rotation Affect Its Shape?
@Serg And so the earth elongates about the equator for the same reason that arms start move away from my sides when I rotate around? If this is true, is there some way to describe this in term of newton's laws, or something of the like?

@Serg How and why does the rotation affect the earth's shape?

comment Elastic Collision And Momentum
@dmckee I believe that is what I was doing, in my other post. I just don't know if I am solving the collision correctly; and I wasn't sure if I could combine non-vector expressions into a vector equation.

Sorry, I did edit my post, and I don't have the capabilities, yet, to offer a bounty. This took me so long to type.

So, are you saying that kinetic energy is represented by the variable p?

comment Elastic Collision And Momentum
How do you derive something like this $p^2/2m$
Nov

comment Elastic Collision And Momentum
I don't understand how you get this part: $p^2/2m_1=m_1gh\rightarrow p=m_1\sqrt{2gh}$

I tried to solve the problem, but was unable to. I edited my post to reflect my attempt, I'd really appreciate it if you could take a gander. Thank you!

comment Elastic Collision And Momentum
So, would it be true, that for the block-earth system--the block I belief the person was referring to was $m_1$--,mechanical energy wouldn't be conserved, since the there is a transfer of kinetic energy from $m_1$ to $m_2$, meaning energy left the block-earth system?

comment A Decrease In Momentum?
@Claudius For your last point, that momentum is transferred to the earth: is this so, because the system is only the rubber ball; and if earth was included in the system, there would be no transfer of momentum out of the system?

comment Momentum And Energy Problem
@Manshearth No, I was asking why internal forces don't affect the total momentum of a system.
