Part A

A $550\mathrm{.}0g$ bird is flying horizontally at $2\mathrm{.}00\frac{m}{s},$ not

paying much attention, when it suddenly flies into a

stationary vertical bar, hitting it $25\mathrm{.}0cm$ below the top

$($Figure $1).$ The bar is uniform, $0\mathrm{.}750m$ long, has a mass

of $2\mathrm{.}50kgkg,$ 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$).$
