The vector position of a 3.50-g particle moving in the xyplane varies in time according to rS15s3i⁄13j⁄dt12j⁄t2, where t is in seconds and rS is in centimeters. At the same time, the vector position of a 5.50 g particle varies as rS253i⁄22i⁄t226j⁄t. At t5 2.50 s, determine (a) the vector position of the center of mass of the system, (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.
