Two bodies of masses 1 kg and 2 kg are located at (1,2) and (-1,3), respectively. Calculate the coordinates of center of mass.

Explanation

To find the coordinates of the center of mass of two bodies with given masses and positions, we can follow these steps:

### Step 1: Identify the masses and their positions
Let:
- Mass \( m_A = 1 \, \text{kg} \) located at coordinates \( (x_A, y_A) = (1, 2) \)
- Mass \( m_B = 2 \, \text{kg} \) located at coordinates \( (x_B, y_B) = (-1, 3) \)

### Step 2: Use the formula for the center of mass
