Two people carry a heavy electric motor by placing it on a light board 1.50{\rm m} long. One person lifts at one end with a force of 370{\rm N} , and the other lifts the opposite end with a force of 680{\rm N}.
Part A What is the weight of the motor?
Part B Where along the board is its center of gravity located? Answer includes " {\rm m} from the end where the 370-{\rm N} force is applied" at the end of it
Part C Suppose the board is not light but weighs 200{\rm N} , 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? Answer includes " {\rm m} from the end where the 370-{\rm N} force is applied" at the end of it.
