5. Two people carry a heavy electric motor by placing it on a light board 2.00 m in length. One person lifts at one end with a force of 700N, and the other lifts the opposite end with a force of 500N. What is the weight of the motor, and where along the board is its center of gravity located? (Note: The center of gravity of an object is the point where the weight passes through.)
