a 250 g block of ice is removed from the refrigerator at -8.0°C. how much thermal energy does the ice absorb as it warms to room temperature (22°C)? (the heat of fusion of water is 334) (specific heat of ice is 2.05 joules/gram) (specific heat of water is 4.184 joules/gram)?

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
