Part A
A 500.0 g bird is flying horizontally at 2.00 m/s, not
paying much attention, when it suddenly flies into a
stationary vertical bar, hitting it 25.0 cm below the top
(Figure 1). The bar is uniform, 0.750 m long, has a mass
of 1.20 kg kg, and is hinged at its base. The collision
stuns the bird so that it just drops to the ground afterward
(but soon recovers to fly happily away).
