A body initial traveling at 10m/s is given a retadation of 2m/s for 3sec. Find its final velocity he bought a New York traveling at 10 m per second is given with addition of to meet up at 7:12 or 3 seconds

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?
