Newton's law of gravitation can be used to show that if an object weighs pounds on the surface of the earth, then its weight at a distance x from the center of the earth is w(x)= (for x≥ where =3960 miles is the radius of the earth. estimate the altitude at which a 120- lb pilot would weigh 119.5 lb. (use decimal notation. give your answer to two decimal places.)

Asimply means that over time there was some sort of change.

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?
