A 4.00kg block slides on the surface of an inclined table, which makes an angle of 15.0∘ with the horizontal. The block is connected through cords over two pulleys to a 7.26kg bowling ball on the upper side of the table, and a 3.00kg ball on the lower side. The pulleys are massless and frictionless, while the coefficient of kinetic friction between the block and the table's surface is 0.470.

  1. Draw a free-body diagram for each moving object.
  2. Determine the direction of motion and acceleration of the system.
  3. Calculate the tension in each cord.
