OK, for #5 I was being dyslexic when I found angular momentum and switched the 5 and the 7 at the end, and I was doing the right thing for finding the work done, I just forgot to convert to KJ. I'm working on the rest now.

I hit post too soon on accident, here is the edit.

On this assignment I could do most of the work easily, I just have some questions on three problems 3. Homework Statement A playground merry-go-round of radius R = 2.00 m has a moment of inertia I = 270 kg·m2 and is rotating at 9.0 rev/min about a frictionless vertical axle. Facing the axle, a...

[SOLVED] Last 3 problems on Rotational Dynamics OK, I've done problems 1-3, but I'm having a real hard time with 4-6. Any help you guys could give me would be greatly appreciated! 4. Homework Statement A block of mass m1 = 2.45 kg and a block of mass m2 = 5.55 kg are connected by a...

Homework Statement The four particles shown below are connected by rigid rods of negligible mass where y = 5.70 m. The origin is at the center of the rectangle. (a) If the system rotates in the xy plane about the z axis with an angular speed of 6.30 rad/s, calculate the moment of inertia of...

Ok, thank you guys very much.

I'm not sure if this is where I post this, I'm kind of new here. But how do you put images in your posts? I tried normal HTML but that didn't work at all.

Thanks Artaxerxes I'm working on it right now, I appreciate the help.
