4. The vector position of a 3.50-8 particle moving in the xy-plane varies in time according to ri = (31+ 3)t +23+, where t is in seconds and Ti is in centimeters. At the same time, the vector position of a 5.50 g particle varies as =31-22 -6ſt. Att - 2.50 s, determine (a) the vector position of the center of mass, (b) the linear momentum of the system, (c) the velocity of the center of mass. (d) the acceleration of the center of mass, and (e) the net force exerted on the two- particle system. (4+3+3+4+4-18,
