Two people carry a heavy electric motor by placing it on a light board 2.60 m long. One person lifts at one end with a force of 450 N , and the other lifts the opposite end with a force of 690N . Suppose the board is not light but weighs 220 , with its center of gravity at its center, and the two people each exert the same forces as before. What is the weight of the motor in this case? Where is its center of gravity located?
