Three objects are connected on the table as shown in the figure. The table is rough and has a coefficient of kinetic friction of 0.350. The objects have masses of 4.00 kg, 1.00 kg, and 2.00 kg, as shown, and the pulleys are frictionless.
(a) Determine the acceleration of each object and their directions.
(b) Determine the tensions in the two cords.
