If I use Iturntable = (0.5)(0.17)(0.15)2, I get Iturntable = 1.9125 * 10-3 kg m2. Plugging this in, I get a final answer of 5.42 rad/s. Does this seem right?

Would it just be 1/2*(.170)(.15)? That's what I had at first, but I wasn't sure if that was correct or not.

I've spent at least an hour trying to figure this out, but can't seem to figure out how to solve this. 1. Homework Statement A 170g , 30.0-cm-diameter turntable rotates on frictionless bearings at 66.0rpm . A 25.0g block sits at the center of the turntable. A compressed spring shoots the block...

Thank you! I think I've got it now.
