13.5 ** A bead of mass m is threaded on a frictionless wire that is bent into a helix with cylindrical polar coordinates (p, p, z) satisfying z = co and p = R, with c and R constants. The z axis points vertically up and gravity vertically down. Using o as your generalized coordinate, write down the kinetic and potential energies, and hence the Hamiltonian H as a function of o and its conjugate momentum p. Write down Hamilton's equations and solve for o and hence 2. Explain your result in terms of Newtonian mechanics and discuss the special case that R=0.

This would be all of g. how do you get just the z component of the gravitational field

Tidal forces are gravitational forces exerted on different parts of a body by a second body. Their effects are particularly visible on the earth's surface in the form of tides. To understand the origin of tidal forces, consider the earth-moon system to consist of two spherical bodies, each with a spherical mass distribution. Let r. be the radius of the earth, m be the mass of the moon, and G be the gravitational constant. Part B Since the gravitational force between two bodies decreases with distance, the acceleration anear experienced by a unit mass located at the point on the earth's surface closest to the moon is slightly different from the acceleration afar experienced by a unit mass located at the point on the earth's surface farthest from the moon. Give a general expression for the quantity anear-afar Express your answer in terms of G, m, r, and re. ▸ View Available Hint(s) anear afar = ΜΕ ΑΣΦ ? x Xb √√x √x X [X] X.10" Variables are case sensitive.
