Were both bodies initially moving, or was one initially stationary? one stationary both moving Which line segment corresponds to the motion of the center of mass before the collision? Which line segment corresponds to the motion of the center of mass after the collision? Is the mass of the body that was moving faster before the collision greater than, less than, or equal to that of the other body? greater than less than equal to
