Since the pulley is a disk that means I = 1/2mr^2 and omega is vfinal/r. I have my equation 1/2(m2 + m1)vfinal^2 + 1/2Iw^2 = m1gh but I don't know what I'm doing wrong.

**bobpursley**, Monday, March 8, 2010 at 8:54pmSolve for I in that equation, then from

knowing the value of I, set it equal to 1/2 masspulley*radius^2 and solve for the masso of the pulley. radius pulley=.12m
