Question

Physics

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.

  1. Draw a free-body diagram for each of the blocks and the pulleyseparately. (??)
  2. Find the magnitude of the acceleration of the blocks. (??)
  3. Find the magnitude of the angular acceleration of the pulley.(??)
  4. Find the magnitude of tensions in the cords, ?1,?2, and ?3. (See the figure.) (??)
