Consider a rectangular coordinate system with origin at the center of the earth z-axis through the North Pole, and -axis through the prime-meridian. Find the rectangular coordinates of London, England (51°32'N, 0°5'W). A minute is 1/60°. Assume the earth is a sphere of radius R 6367 km. London has coordinates -914.56,4341.06,4567) Usage: To enter a point, for example (x, y, z), type "(x, y, z)"

do i solve this?
Part I Angular Momentum 1. Find the angular momentum of a rectangular box (dimensions X XY) rotating about its center of mass (mass m). Assume the box has angular velocity w and the center of mass is located at the origin. If the rotation axis changes to the point (x, y) away from the center of mass how would the angular momentum change?

Problem 4 A square object is constructed of four identical uniform thin sticks, each of mass m and length L, attached together. This object is hung on a hook at its upper corner. If it is rotated slightly to the right and then released, at what frequency will it swing back and forth? Hints: Find the distance from the hook to the center of mass of the object. Then find the moment of inertia of each stick with respect to...
