Thank you very much for posting your comment. You're absolutely right that the answer is times 10 to the 4, not times 10 to the 8. The quick answer has been updated, and the video, which is correct up until the final answer, will be updated later when I get a chance.

this answer does not match the back of the book....please change

If you plug (15000/2) (3.6667) into your calculator you get the book's answer.

Hi nelson.cynthia,

Thank you very much for posting your comment. You're absolutely right that the answer is times 10 to the 4, not times 10 to the 8. The quick answer has been updated, and the video, which is correct up until the final answer, will be updated later when I get a chance.

Good luck with your studies, and thank you again!

I am confused on why you would use the AVERAGE angular velocity rather than just the final. I cannot find this formula in the book.
