Question:

A pendulum consists of two 3.2-kg concentrated masses positioned as shown on a light but rigid bar. The pendulum is swinging through the vertical position with a clockwise angular velocity ω = 6 rad /s when a 50-g bullet traveling with velocity v = 300 m /s in the direction shown strikes the lower mass and becomes embedded in it. Calculate the angular velocity ω′ which the pendulum has immediately after impact and fi nd the maximum angular deflection θ of the pendulum.
