To find the center of mass of the system of three particles located at the corners of an equilateral triangle, we can follow these steps: ### Step 1: Define the coordinates of the particles Let's assign coordinates to the corners of the equilateral triangle ABC: - Mass \( m_1 = 1.0 \, \text{kg} \) at point A (0, 0) - Mass \( m_2 = 2.0 \, \text{kg} \) at point B (0.5, \( \frac{\sqrt{3}}{2} \)) since the height of the triangle is \( \frac{\sqrt{3}}{2} \) when the base is 1 meter. - Mass \( m_3 = 3.0 \, \text{kg} \) at point C (1, 0) ...
