**Learning Goal:**

Once you have decided to solve a problem using Newton's 2nd law, there are steps that will lead you to a solution. One such prescription is the following:

- Visualize the problem and identify special cases.
- Isolate each body and draw the forces acting on it.
- Choose a coordinate system for each body.
- Apply Newton’s 2nd law to each body.
- Write equations for the constraints and other given information.
- Solve the resulting equations symbolically.
- Check that your answer has the correct dimensions and satisfies special cases.
- If numbers are given in the problem, plug them in and check that the answer makes sense.
- Think about generalizations or simplifications of the problem.

As an example, we will apply this procedure to find the acceleration of a block of mass \( m_2 \) that is pulled up a frictionless plane inclined at angle \( \theta \) with respect to the horizontal by a massless string that passes over a massless, frictionless pulley to a block of mass \( m_1 \) that is hanging vertically. ([Figure 1](#))

**Figure:**

The diagram illustrates a system with two blocks connected by a string over a pulley. 

- **Block 2** is on an inclined plane, angled at \( \theta \), which is represented as a slope. 
- **Block 1** is hanging vertically. 

The string connecting the blocks is shown passing over a pulley. The setup demonstrates a common problem in physics involving inclined planes and pulleys to analyze forces and acceleration.

**Text Explanation:**

The task is to determine the acceleration of a block of mass \( m_2 \), which is pulled up a frictionless inclined plane at an angle \( \theta \) using a massless string that is connected to a block of mass \( m_1 \). This mass \( m_1 \) hangs vertically from a massless, frictionless pulley. Reference Figure 1 for visual details.

**Figure Description:**

The figure is divided into four labeled diagrams (a, b, c, d), each illustrating forces and components for two blocks.

- **Diagram (a):**
  - Block labeled "2" with forces shown: gravitational force (\( m_2g \)), normal force, and tension \( T_2 \).
  - The inclined plane is marked with angle \( \theta \).

- **Diagram (b):**
  - Block labeled "1" with gravitational force (\( m_1g \)), and tension \( T_1 \) acting vertically.

- **Diagram (c):**
  - Free-body diagram for Block 1: Shows tension \( T_1 \) and gravitational force \( m_1g \).

- **Diagram (d):**
  - Free-body diagram for Block 2: Shows decomposed force components parallel and perpendicular to the inclined plane, tension \( T_2 \), and gravitational force (\( m_2g \)).

**Problem Part G:**

The task is to write equations for the constraints and given information in this system. The problem outlines a constant string length, correlating accelerations of blocks. You need to find a relationship between the x-component of Block 2's acceleration (\( a_{2x} \)) and Block 1's acceleration. Careful attention to sign conventions is advised.

Hydrated blocks of information on available hints are provided.

**Problem Solver Instructions:**

- Express \( a_{2x} \) in terms of \( a_{1x} \) and/or \( a_{1y} \), components of the acceleration vector for Block 1.
- Use the input field on the website to enter the equation and click "Submit."

**Continued Learning:**

Part H is accessible after completing the current task with a focus on further problems or feedback.
