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 red/s when a 50-g bullet traveling with velocity υ = 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 find the maximum angular deflection θ of the pendulum
