In a game at the county fair, a board of length 0.258 m and width 0.438 m , with mass 2.37 kg , hangs vertically. The person playing the game throws a small ball at a target drawn on the center of the board. With your great skill, you are able to strike the target at the exact center of the board using a ball of mass 0.431kg . The ball was moving perfectly horizontally when it struck the target with a speed 7 72 m /s before it bounced off elastically PartA * PartB What is the angular velocity of the board after the collision? (Since the ball is so small, you can treat it like a point mass.) b View Available Hint(s) Part C What is the speed of the ball immediately after the collision? HA m Of = Value S
