Where is its center of gravity located

Reference no: EM13303901

Two people carry a heavy electric motor by placing it on a light board 2.70m long. One person lifts at one end with a force of 380N , and the other lifts the opposite end with a force of 640N .

Part A What is the weight of the motor?

Part B Where along the board is its center of gravity located?

Part C Suppose the board is not light but weighs 180N , 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?

Part D Where is its center of gravity located?
