A 32 Newton force is applied to an arrangement with the box on the left having mass 5 kilogram and the box on the right having mass 3 kilogram.
(a) Determine the acceleration of the system and
(b) Determine the tension in the cord connecting the boxes.
(c) Check that Newton second law of motion is satisfied for the 3 kilogram box.
