In the figure below, the masses of each object are: m₁ = 2.00 kg, m₂ = 2.00 kg, m³ = 3.00 kg. The labeled distances are: d₁ = 30.0 cm, d₂ = 106 cm, d3 = 60.0 cm (where d is the x distance for the center of the block). The height of each block is h₁ = 21.0, h₂ = 28.0 cm, and the h3 = 11.0 cm. Assume the center of mass for each individual object is at the center of the object. Hint: Consider the final center of mass (x,y) relative to the axes shown in the figure. Note the positions of the boxes relative to the axes and to one another. Determine the positions, x and y, of the center of mass for the system below. y Enter to 3 significant figures Center of mass (x, y): ( d1 m1 d3 d2 h1 cm m3 m2 h2 11h³ X ✔cm) Think and Prepare 1.
