A boy of mass 23 kg sits on a seesaw 1.5 m from the axis of rotation. At what
distance from the axis of rotation must his friend, whose mass is 21 kg, be
positioned to balance the seesaw? [6 marks]

  • physics -

    Equate moments about fulcrum:
    23*1.5=21*x
    Solve for x.

  • physics -

    I think its 1.64 metres
