Problem 4 Two blocks of masses m and m2 are attached to each other via a string that is wrapped around a disk of mass M and radius R. The system is released from rest. Calculate the common speed of m and and m2 when m2 descends a distance h. (Hint: When m moves down a distance h, m moves up a distance h. I = (MR2)/(2) for the disk.) m g R R P m8
