Meriam, Kraige & Bolton — Kinetics of Systems of Particles: Problem 4_80

4/80 A 60-g bullet is fired horizontally with a velocity \( v = 300 \text{ m/s} \) into the slender bar of a 1.5-kg pendulum initially at rest. If the bullet embeds itself in the bar, compute the resulting angular velocity of the pendulum immediately after the impact. Treat the sphere as a particle and neglect the mass of the bar. Why is the linear momentum of the system not conserved?
