Three blocks move on a frictionless surface with a 56 N force acting on the 12 kg block as shown. Determine (a) the acceleration of the total system, (b) the tension in the cord connecting the 12 kg and the 3 kg blocks, and (c) the normal force exerted by the 3 kg block on the 1 kg block. I am especially confused by part c) I would really appreciate it if you could explain clearly. I originally thought (3kg)(acceleration), but would it be (1kg) (acceleration) for the Normal force exerted by the 3kg block on the 1 kg block instead?
