I'm having trouble getting the rigth answer for part A. It's telling me that I am off by a multiple of ten, but I've moved the decimal to the right and left, but it's still not right. Maybe I'm doing the problem wrong. Could anyone give me a formula or way to solve this problem?
A 15g CD with a radius of 6cm rotates with an angular speed of 24 rad/s.
A. What is its kinetic energy?
B. What angular speed must the CD have if its kinetic energy is to be doubled?
