Three objects are located in the x-y plane as shown in the figure below. Determine the x coordinate of the center of mass for this system of three objects. Note the masses of the objects: ma = 6.0 kg, mg = 2.0 kg, and mc = 4.0 kg. 16 14 B ONADOSE 0 2 4 6 8 10 12 14 16 O 7.6 O 8.9 O 6.3 O 5.6 O 8.3Bird A, with a mass of 2.2 kg, is stationary while Bird B, with a mass of 1.7 kg, is moving due north from Bird A at 3 m/s.
