The cheetah is one of the fastest accelerating animals, for it can go from rest to 28.0 m/s in 5.20 s. if its mass is 100 kg, determine the average power developed by the cheetah during the acceleration phase of its motion. express your answer in (a) watts and (b) horsepower.

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?
