Question
At this maximum height (.44m) the ball hits a rectangular piece of wood which is free to pivot about a rod running horizontally through its center. The wood has a mass of 0:02 kg, a length of 2:0 cm, and a height of 5:0 cm. The width of the wood is negligible. The ball hits the wood halfway between the top edge and the pivot bar causing the wood ap to rotate. If the ball's velocity decreases to one quarter of its initial value, what is the angular velocity of the wood? You can assume that the moment of inertia of a rectangular slab is the same as that for a long thin bar.Explanation / Answer
unable to understand the question if u can please post the figure
