Two blocks of masses?1 = 700 ? and ?2 = 1100 ? are connected by acord of negligible mass and hung over a disk- shaped pulley, asshown in the figure. The pulley has a mass of
? = 1.50 ?? and aradius of ? = 14 ??, and rotates about a light- weight axle throughits center. The axle itself is hung from the ceiling by two likecords of negligible mass and is held horizontally. The system isreleased from rest.
- Draw a free-body diagram for each of the blocks and the pulleyseparately. (??)
- Find the magnitude of the acceleration of the blocks. (??)
- Find the magnitude of the angular acceleration of the pulley.(??)
- Find the magnitude of tensions in the cords, ?1,?2, and ?3. (See the figure.) (??)
