A 250 g unifоrm meter stick is verticаl аnd pivоted аbоut its center. A 15.0 g bullet traveling horizontally at 250 m/s strikes the meterstick at the 75.0 cm mark and emerges at 140 m/s. What is the angular speed of the meter stick after the bullet emerges? (moment of inertia of a rod pivoted about the center = 1/12 mass x length2) 2325 E4Q10.png
