This text is presented for educational purposes, prompting students to engage with physics concepts regarding forces and friction on interacting objects.

The image illustrates a physics problem involving two blocks connected by a massless string that passes over a frictionless pulley.

- **Blocks Overview**:
- A vertical block labeled “2.0 kg” is positioned on top of a horizontal block labeled “4.0 kg.”
- Both blocks are connected by a string, with the pulley system positioned on the right side.

- **Forces and Directions**:
- An arrow labeled \( \vec{P} \) points to the left, indicating the direction of an external force applied to the 4.0 kg block.
- Coordinate axes labeled \( x \) and \( y \) indicate the directions for horizontal and vertical movement, respectively.

- **Pulley System**:
- The image shows a cylindrical, frictionless pulley attached to a vertical surface, around which the string is wrapped.

This setup is used to analyze the dynamics of the blocks and the effect of forces and tension in the system.
