Askier descends a mountain at an angle of 35.0º to the horizontal. if the mountain is 235 m long, what are the horizontal and vertical components of the skier's displacement? (use trigonometry to solve.) x = y = .

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?
