Two connected carts are pulled across the floor under the influence of a force of 36 N applied by a string. The first cart and its contents have a mass of 10 kg, and the second cart and contents have a mass of 8 kg. We’ll assume that friction is very small and can be neglected. What force would you have to apply to the first cart only to get it to move with the same acceleration?
