It's a pulley problem. The wheel is actually a pulley. The cord is wrapped around the pulley, and from the free end of the cord hangs a block. As the block falls and pulls the cord, the wheel rotates faster and faster. The question asks for the velicity of the block just as it hits the floor.
Here's the problem statement from Crash again:
Crash writes:
There is a wheel of r = 0.38m and m = 1.3kg and attached to that wheel from a cord is a 0.70kg block that is 1.2m off the ground. If the block is released from rest, what speed will it have just before it hits the floor if there is no friction at the wheel's axis?
Crash only presented the problem to you because you said this:

I have a common sense understanding of science and physics way beyond any jerk scientist that went to 8 years of college, just because I can look around at things at see whats going on.
But you didn't even recognize it as a pulley problem, let alone provide a solution.
Anyone who devotes a considerable proportion of his life to something, as "jerk scientists" do to science, are bound to become pretty good at it. Crash was trying to make the point that scientists actually know some stuff (a lot of stuff, actually) that you don't about science.
There's no harm in not knowing something. Most of us know almost nothing about everything. But I think Crash's attention was caught by the incongruity of your statement given the level of knowledge demonstrated in your posts so far.
