A girl runs once around a circular track with a radius of 65m at a speed of 2m/s. Her displacement is:

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

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?
