two people carry a heavy electric motor by placing it on a light board 2m long.one person lifts at one end with a force of 700N, and the other lifts the opposite end with a force of 400N.Calculate the weight of the motor and determine where its center of Gravity is Located

  • physics - ,

    weight = 700 + 400 = 1,100

    x is distance from the strong person
    1100 x = 400(2)
    x = 8/11 meters from the person lifting with 700 N
