A store clerk pulls three carts connected with two horizontal cords to move products from the storage
room to the display shelves. The masses of the loaded carts are: 1 m =15 kg; 2 m =13.2 kg; and
3 m =16.1kg. Friction is negligible. A third cord, which
pulls on cart 1 and is at an angle of 21.0° above the
horizontal, has a tension of magnitude 35.3 N.
Determine the magnitude of
a. the acceleration of the carts
b. the tension in the last cord
c. the tension in the middle cord

Question
