Problem 1 (20 points) Part A A pendulum consists of two 3 . 5 kg concentrated masses positioned as shown on a massless but rigid bar. The pendulum is swinging through the vertical position with a clockwise angular velocity ω = 5 rad/s when a 50g bullet traveling with velocity v = 350 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 Fnd the maximum angular deﬂection φ of the pendulum. Part B ±or the pendulum in Part A, Fnd the impulse acting on the support pivot at the instant of impact; acting on the rod at the boundary between the rod and the upper mass at the instant of
