A store clerk pulls three loaded shopping carts connected with two horizontal cords to help customers load their carts. Cart 1 has a mass of 9.1 kg, cart 2 has a mass of 12 kg, and cart 3 has a mass of 8.7 kg. Assume friction is negligible. A third cord, which pulls on cart 1 and is at an angle of 23 degrees above the horizontal, has a tension of magnitude 29 N. a) Find the magnitude of the acceleration of the carts.
b) Find the magnitude of the tension in the cord between cart 2 & 3.
c) Find the magnitude of tension in the cord cart 1 & 2
