A pendulum consists of two 3.1-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 w = 4.2 rad/s when a 51-g bullet traveling with velocity 330 m/s in the
direction shown strikes the lower mass and becomes embedded in it. Calculate the angular velocity w (positive if counterclockwise,
negative if clockwise) which the pendulum has immediately after impact and find the maximum angular deflection 8 of the pendulum.
Assume a - 195 mm, b = 420 mm, = 15°.
