The two people carry a heavy electric motor by placing it on the light board 2.70 long. One person lifts at one end with a force of around 410, and the other lifts the opposite end with a force of around 650.
i) Determine the weight of the motor?
ii)) Where along the board is its center of gravity positioned?
iii) Assume that the board is not light however weigh 200, with its center of gravity at its center, and the two people each exert the similar forces as before. Determine the weight of the motor in this case?
iv)Where is its center of gravity positioned?
