A person on horseback is on a drawbridge which is at an angle = 20.0° above the horizontal, as shown in the figure. The center of mass of the person-horse system is d = 1.35 m from the end of the bridge. The bridge is l = 7.00 m long and has a mass of 2,300 kg. A cable is attached to the bridge 5.00 m
from the frictionless hinge and to a point on the wall h = 12.0 m above the bridge. The mass of person plus horse is 1,100 kg. Assume the bridge is uniform. Suddenly (and most unfortunately for the horse and rider), the ledge where the bridge usually rests breaks off, and at the same moment the cable
snaps and the bridge swings down until it hits the wall.

(a) Find the angular acceleration (magnitude, in rad/s²) of the bridge once it starts to move.

The mass of a particular eagle is twice that of a hunted
pigeon. Suppose the pigeon is flying north at Vi2 = 16.1 m/s
when the eagle swoops down, grabs the pigeon, and flies off.
At the instant right before the attack, the eagle is flying
toward the pigeon at an angle 0 = 64.3° below the horizontal
and a speed of Vi,1
= 37.9 m/s.
What is the speed of of the eagle immediately after it catches
its prey?
