A bird perched on a swing has a mass of 62.8 g. The base of the swing has a mass of 118.0 g . Assume that the swing and the bird are originally at rest and that the bird then takes off in a horizontal direction at 2.18 m/s. If the base can swing freely (i. e., without friction) around the pivot, how high (in cm) will the base of the swing rise above its original level?
