Center of mass

  1. Mar 10, 2008 #1
    When empty, a 166 kg rowboat is symmetrical. A boy of mass 70.5 kg sits 2.1 m from the center of mass of the rowboat toward the front of the boat, and a girl of mass 68.8 kg sits 2.38 m from the center of mass of the rowboat toward the rear of the boat. Find x, distance from center mass of the emptyt rowboat to the center of mass of the rowboat-plus-kids system.


    Xcm=(M1X1+M2X2)/(M1+M2)



    what's the center mass of the empty rowboat?


    (70.5*2.1+68.8*2.38)/(166+70.5+68.8) is it the center of mass of the rowbot-plus-kids system??

    please help me . thanks a lot
