5. [0/2 Points] DETAILS PREVIOUS ANSWERS The mass and coordinates of three objects are given below: m = 6.0 kg at (0.0, 0.0) m, m2 = 1.2 kg at (0.0, 3.9) m, and m3 = 4.0 kg at (3.2, 0.0) m. Determine where we should place a fourth object with a mass m (0.0, 0.0) m. y 0.0 MY NOTES ASK YOUR TEACHER 8.4 kg so that the center of gravity of the four-object arrangement will be at See if you can write an expression for the x coordinate of the center of mass of the four objects in terms of known quantities and the x coordinate of the fourth object and then solve for the x coordinate of the fourth object. m m Additional Materials Reading
