d A B 1 of 1 A pendulum consists of a slender rod, AB, of mass m, = 3.80 kg and a wooden sphere of mass mg = 13.0 kg. (Figure 1) The length of the rod is d = 2.40 m and the radius of the sphere is R = 0.145 m. A projectile of mass mp = 0.110 kg strikes the center of the sphere at a velocity of v = 280 m/s and becomes embedded in the center of the sphere. What is w, the angular velocity of the pendulum, immediately after the projectile strikes the sphere? Express your answer numerically in radians per second to three significant figures. View Available Hint(s) w = 0.849 rad/s Submit Correct Correct answer is shown. Your answer 0.84 rad/s was either rounded differently or used a different number of significant figures than required for this part. Part C What is, the maximum angle measured from the vertical that the pendulum will swing, after the projectile impacts the pendulum? Express your answer numerically in degrees to three significant figures.
