Having recently completed her first physics course, dawn well has devised a new business plan based on her teacher's physics for better living theme. sawn learned that the objects weigh different amounts at different distances from earths center. her plan involves buying gold by the weight at one altitude and then selling it at another altitude at the same price per weight. should dawn buy at a high altitude and sell at a low altitude or vice versa"?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
