# Physics Problem on centre of mass

#### TutaA

Figure 4 shows three point masses glued to the vertices of a massless triangle of side L=2.0 m. Two of the massess are m=0.75kg and the other mass is twice that value, as shown in the figure. The device is allowed to rotate about point A in a verticle plane about the centre of the larger mass, 2m. Give the x and y coordinates of the centre of mass of the device in the coordinate system

$\bar{x} = \dfrac{\sum m_i x_i}{\sum m_i}$

$\bar{y} = \dfrac{\sum m_i y_i}{\sum m_i}$
