Ah I see what you mean now. We both misinterpreted the problem, thanks for working through it with me!

It is to me, too! No problem!

mbcrute, I found this link very useful in solving this exact same problem. It has explanations, which I can't follow all that well, but they are there. http://web.mit.edu/8.01t/www/materials/modules/old_guide/guide16Appendix.pdf It gave me the correct answer.

What would be the difference? Isn't the angular acceleration constant and the radius constant, thus making the linear acceleration constant for any point on the disk at that radius?

Because mastering physics says it is incorrect :/

Oh! My fault! It's asking: What is the resultant linear acceleration of a point on the rim of the disk at the instant when the disk has turned through 0.100rev ?

Homework Statement A uniform disk with radius 0.390m and mass 27.0kg rotates in a horizontal plane on a frictionless vertical axle that passes through the center of the disk. The angle through which the disk has turned varies with time according to θ(t)=( 1.50rad/s)t+( 9.00rad/s2)t2 . What is...

Okay, I see now! So the net force acting on the 2 kg block is simply the spring force directed to the right. Thank you!

I overreacted, for which I apologize.

If you knew it was experimentally proven why did you come here acting like you came up with the experiment? Trying to get brownie points with strangers? If you wanted to discuss the phenomenon you should have just posted that link right off the bat.

It acts on the 8 kg mass, the picture was as such: [2 kg]--(spring)--[8 kg]--> 4.0 N And thank you for the welcome! :)

I'm confused about this part. Let's say we're looking at two individual particles - the electrons are closer to the other electrons than they are to the nuclei, so I don't see how the similar charges are slightly more distantly separated. Maybe if you are only accounting for the protons, but the...

This problem was on my test today and I am not sure if my solution is correct. Homework Statement A box of mass 2 kg and another of mass 8 kg are attached by a spring with a spring constant of 80 N/m. A 4.0 N force is applied to the 8 kg box. Both of the boxes move with a constant...
