? constant acceleration equations I guess
The Attempt at a Solution
They didn't get to this part in class today, yet it's expected on our online homework due tonight. No idea how to even get started.
jtw2e: Your post title makes my think you might not yet have been introduced to rotational kinetic energy. For an alternate approach: consider the relationship between how fast the block lands and how fast the disk rotates. Do you see that you can work out the torque acting on the disk and find the rotational speed?For these questions you can consider conservation of energy.
PE + KE = constant.
Thank you. As of today we began rotational kinetic energy but did not get very much covered in the topic. We are supposed to begin torque on Friday.jtw2e: Your post title makes my think you might not yet have been introduced to rotational kinetic energy.

While I would like to use CoE, we're supposed to find our answers with rotational constant acceleration approach. I've actually been doing my other homework with CoE just to get the answers turned in. I don't know how to find them with this rotational stuff.For these questions you can consider conservation of energy.
PE + KE = constant.
