If they hold on to the two ends of a rope, and the man pulls the rope so he moves 2 meters, how close is he to the woman now? c. How far will the man have moved when he collides with the woman? 6 m ...
(i) To find center of mass from the origin: The point masses are at positions, x 1 = 4 m, x 2 = 8 m from the origin along X axis. The center of mass x CM can be obtained using equation 5.4. The center of mass is located 6.5 m from the origin on X-axis. (ii) To find the center of mass from 3 kg mass: The origin is shifted to 3 kg mass along X-axis.
