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 Kinetic Energy And Rotational Motion
So, the only problem I had with my approach is the miscalculation of the translational velocity? Would I still have to use a force approach to find the acceleration of the can?

comment Finding Rotational Kinetic Energy Of A Clock
Even with the corrected values, I still get a wrong answer. The answer yielded from the calculations above is $3.80\cdot 10^{-4} J$, which is wrong.

comment Tensions And Pulleys With Masses
I actually figured it out. However, I have a new question: if the tension forces on either side of the pulley are different, then why is there only one acceleration for the two blocks and the particles on the outer rim of the pulley?

comment Tensions And Pulleys With Masses
I've sort of run into a road-block trying to solve this problem. I try to solve for the acceleration, but I have no way of eliminating the unknowns from my equations; what still remains is the two tensions forces. So, I tried to figure out how they were related through torque on the pulley; and despite the fact that there is a relationship, it introduces another unknown, namely, the torque. How do I solve for the acceleration?

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?

Why is the height not needed, though?

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.

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

How do you derive something like this $p^2/2m$
