Item 4 This is a problem that utilizes the concept of center of mass: Two people, one of mass 90 kg and the other of mass 60 kg. sit on the two ends of a rowboat of mass 79 kg and length 2.6 m. The mass of the boat is uniformly distributed along its length. The heavier person is initially sitting on the left end and the lighter person on the right end. ▼ Part B Now the two people exchange seat. After the exchange, the heavier person is now sitting on the right end and the lighter person on the left end. Calculate the position of the center-of-mass for the system (boat + 2 people) again. How far is it from the left end of the boat now?
