A ball with a mass of 5 kilograms collides with a rod in a vertical position with a frictionless hinge at its base. The rod has a mass of 50 kilograms and is 1.36 meters long. The ball has a velocity of 30 meters per second initially (the left) and bounces off with a speed of 15.3 meters per second (the right). Assume energy is not conserved. Part A: What is theangula rvelocity of the rod immediately after the collision? Part B: Whatis the angular velocity of the rod at the bottom, after it has rotated 180 degrees?
