Wait, never mind. I just figured out the problem. Thanks.

That explains part of my error, but even then I still can't see how to set this system up.

I thought that was the force of gravity acting on the 5 kg box. F = ma, so 5g = 49.05 I also thought that was the force acting on the pulley to create torque.

It's 5 kg, and it's one of the values given in the initial problem. Honestly, I don't even know what going on in this problem anymore, and I don't see the point in playing with my setup, since it's obviously wrong.

Even then the acceleration comes out to 39.8 m/s2, and the answer is still wrong. I think my whole system is set up incorrectly.

Here's what I tried: F = ma; so a = F/m τ = rF = Iaθ; and aθ = ratan; τ = Iratan; atan = τ/Ir = rF/Ir = F/I and F should be the force the hanging box exerts on the pully (F = mg), so: atan = Fg/I So, if a is the same for all parts of the system, then: Th/12 = Tv/5 = Fg/I But Fg = 49.05 and...

So I've been prepping for my Engineering Physics 1 final, and I've been having trouble with rotational motion problems, but this problem has been driving me crazy for the past two days: Homework Statement (I wanted to include a normal link to an image, but I'm a new member, so here's...
