Carl (mc=35 kg) and diane (md=28 kg) are sitting on a wagon (mwagon = 22 kg) that starts at rest (carl and diane are fixed to the wagon, which pushes and pulls them along with the wagon). diane throws a ball (mball=1.5 kg) to carl. diane throws the ball so that it has a momentum of 34 kg m/s to the left, causing the wagon to move to the right at 0.4 m/s.

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?
