6. A pendulum consists of two 3-kg concentrated masses positioned on a light rigid bar which rotates about a horizontal axis through the frictionless bearing O in a vertical plane. The pendulum is initially at rest when a 60-g bullet traveling with velocity v 80 m/s in the direction shown strikes = = : 0.3 m, calculate the angular the lower mass and becomes embedded in it. If a = 0.6 m and b velocity of the pendulum immediately after impact and find the maximum angular deflection 0 of the pendulum. (w = 2.10 rad/s, 0 = 47.9) V a b 6.
