**Problem 2: Gravitational Field Analysis**

A mass \(m_A\) creates a gravitational field. Use the diagram below to answer the following questions. Position vector \(\vec{r}\) defines a location of interest.

Given:
- \(|\vec{r}| = 136 \, \text{m}\)
- \(m_A = 3.2 \times 10^{14} \, \text{kg}\)

**Diagram Description:**
- The diagram shows a position vector \(\vec{r}\) at an angle of 67° from the negative x-axis towards the negative y-axis.
- \(m_A\) is located at the origin of the coordinate system.

**Coordinate System:**
- Positive \(x\) direction points to the left.
- Positive \(y\) direction points upwards.
- Positive \(z\) direction points out of the page.

**Questions:**

a) **Component Form of \(\vec{r}\):**  
Put the position vector into component form using the given Cartesian coordinate system. Show all steps to receive full credit.

b) **Unit Vector \(\hat{r}\):**
