18. 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 m₁=15.0kg; m2=13.2kg; and m3=16.1kg. Friction is negligible. A third cord, which pulls on cart 1 is at an angle of 21.0° above the horizontal, has a tension of magnitude 35.3N. Determine: a. the acceleration of the carts [2 marks] b. the tension in the last cord [2 marks] c. the tension in the middle cord [2 marks]
