David and his father sat at the end of a see-saw 2 m from the pivot. where should David's mother sit in order to balance the see-saw

  • physics - no idea -

    Hard to say with that little information about masses.

  • physics -

    Force multiply by distance(1)+ force multiply by distance(2)= force multiply by distance(3)
    400N multiply by 2m + 600d =700N multiply by 2m
    800+600d=1400
    600d=1400-800
    600d=600
    d=1m
