Q. A 2.22 kg particle has the xy coordinates (-1.29 m, 0.221 m), and a 5.18 kg particle has the xy coordinates (0.764 m, -0.297 m). Both lie on a horizontal plane. At what (a)x and (b)y coordinates must you place a 4.50 kg particle such that the center of mass of the three-particle system has the coordinates (-0.629 m, -0.107 m)?

Q. A uniform disk of radius 0.46 m is mounted on a frictionless, horizontal axis. A light cord wrapped around the disk supports a 0.58 kg object. When released from rest the object falls with a downward acceleration of 4.1 m/s squared.
