... predators. But they serve another function as well. If a hedgehog falls from a tree—a not uncommon occurrence—it simply rolls itself into a ball before it lands. Its thick spines then cushion the blow by increasing the time it takes for the animal to come to rest. Indeed, hedgehogs have been observe ...

... so the angular velocity increases because L = I ω stays constant. Once she passes the center and gets closer to the opposite edge the moment of inertia increases until it is the same value as initially. So the angular velocity also then decreases until reaching is initial value. Assess: How much the ...
