Homework Statement
An Atwood's machine consists of two masses, m1 and m2, connected by a string that passes over a pulley.
If the pulley is a disk of radius R and mass M, find the acceleration of the masses.
Express your answers in terms of variables m1,m2, M, R, and appropriate constants
Homework Equations
T-mg=ma
The Attempt at a Solution
a=-g/(1+I/(m1+m2)R^2
this is an equation i found but i am not sure what to do with I
