Transcribed Image Text: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.) Provide illustration and free body
