Point P is located on the outer surface of the top, a distance h = 29.0 mm h=29.0 mm above the ground. The angle that the outer surface of the top makes with the rotation axis of the top is θ = 19.0 ∘ . θ=19.0∘. If the final tangential speed v t vt of point P is 1.45 m/s, 1.45 m/s, what is the top's moment of inertia I ?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
