Abird (mass m = 500 gram) is flying horizontally at a speed of v0 = 4.00 m/s, when it suddenly hits a stationary vertical bar at 50 cm below the top end of the bar. the bar is uniform with a mass m = 1.5 kg and a length l = 1.00 m. the bar is hinged at the bottom end and is free to rotate about this pivot point. the collision stuns the bird, which then drops vertically to the ground.
what is the angular velocity of the bar just after it is hit by the bird, and what is the angular velocity of the bar just as it reaches the ground?
