The bird perched on the swing in the figure has a mass of 56 g, and the base of the swing
has a mass of 179.2 g. Assume that the swing
and the bird are originally at rest and that the
bird then takes off horizontally at 2.38 m/s.
The acceleration of gravity is 9.8 m/s^2

If the base can swing freely (without friction) around the pivot, how high will the base
of the swing rise above its original level?
Answer in units of m.
