Consider a teeter-totter that is made out of pine, shown below. A pineapple sits on one side of the teeter-totter, a distance 1.09 m from the pivot point, while an apple (non-pine) sits on the other side, a distance of 2.63 m from the pivot. If the pineapple has a mass 132 g, what must the mass of the apple be in order to balance the teeter-totter (i.e. to maintain rotational equilibrium)?

Question
Consider a teeter-totter that is made out of pine, shown below. A pineapple sits on
one side of the teeter-totter, a distance 1.09 m from the pivot point, while an apple
(non-pine) sits on the other side, a distance of 2.63 m from the pivot. If the
pineapple has a mass 132 g, what must the mass of the apple be in order to balance
the teeter-totter (i.e. to maintain rotational equilibrium)?
