**3. Problem Statement:**

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.

**Diagram Explanation:**

The diagram depicts three blocks aligned on a frictionless horizontal surface. From left to right, the blocks have masses: 3 kg, 1 kg, and 12 kg. 

- The 3 kg block is tan in color.
- The 1 kg block is blue.
- The 12 kg block is green.

A horizontal force of 56 N acts to the right on the 12 kg block. A cord connects the 12 kg block to the 3 kg block, passing over the 1 kg block that lies in between. The 1 kg block is not connected by any cord and simply sits between the other two blocks.

This setup illustrates the concept of force and motion, showing how a force applied to one block influences connected blocks in a system.
