Auniform, 4.5-kg, square, solid wooden gate 1.5 m on each side hangs vertically from a frictionless pivot at the center of its upper edge. a 1.1-kg raven flying horizontally at 5.0 m/s flies into this door at its center and bounces back at 2.0 m/s in the opposite direction. (a) what is the angular speed of the gate just after it is struck by the unfortunate raven? (b) during the collision, why is the angular momentum conserved but not the linear momentum?
