Please guys, if that's not how the equation is properly set up PLEASE show me the proper way to set it up. Step by step. My mind doesn't work algebraically, I'm very verbal. I don't even know how I got the proper answer...

ok. Sorry for being so incredibly dense, this problem is just very difficult for me. Here's what I just did. If I made any mistakes please correct them specifically. I drew a diagram showing the forces on the mass (F upwards and m2g downwards) (m2 is meant to be "m subscript 2"), and the...

The rotational inertia is (1/2MR^2) if I'm thinking correctly.

ok, I'm pretty sure that I got the answer. I added the MG of the falling mass to the moment of inertia of the pulley, set that equal to MA and divided that value by the mass of the pulley. I ended up with about 3 m/s^2. If that's not the right answer, please show me how to get the right one...

the rope isn't attached to anything else though, as far as i know, it is only restricted by the acceleration of the pulley. my guess would be to find the angular acceleration of the pulley, then subtract it from the acceleration of the mass due to gravity?

i'd appreciate if i could get an actual set equation from the mentors, instead of hints. I'm a junior in high school, and this isn't a graded homework problem. i just need to know the entire equation is set up for the test tomorrow (my physics teacher couldn't solve this problem, but something...

could you help me a bit more by giving the equations? i'd really appreciate it thanks

PLEASE HELP ME! Pulley-Mass Problem Ok guys, here's the problem. A 1.53kg mass hangs on a rope (negligible mass) wrapped around a frictionless pulley of mass 7.07kg. The radius of the pulley is .66 meters. What is the acceleration of the mass? update! in response to berkeman's post...
