A bug flying horizontally at 2 m/s collides and sticks to the end of a uniform stick hangingvertically from its other end. After the impact, the stick swings out to a maximum angleof 10.0° from the vertical before rotating back. If the mass of the stick is 15 times that ofthe bug, calculate the length of the stick (in m).

In the instant of the figure, two particles move in an xy plane. Particle P₁ has mass 7.40 kg and speed v₁ = 1.91 m/s, and it is at distance d₁ = 9.52 m from point O (the figure is not drawn to scale). Particle P₂ has mass 2.73 kg and speed v2 = 2.37 m/s, and it is at distance d₂ = 8.89 m from point O. What is the magnitude of the net angular momentum of the two particles about O?

Some dragonflies splash down ontothe surface of a lake to clean themselves. After this dunking, thedragonflies gain altitude, and then spin rapidly at about 1000 rpmto spray the water off their bodies. When the dragonflies do this“spin-dry,” they tuck themselves into a “ball” with a moment ofinertia of 2.6 * 10-7kg·m2. How much energy must the dragonflygenerate to spin itself at this rate?
