3. We've primarily looked at closed orbits of planets, but a lot of what we've done can be used to treat projectiles and particle collisions under central forces. For example, a projectile of mass m is launched from a very large distance away with energy E toward a spherical planet of mass M >> m and radius R. Show that the maximum value of the angular momentum for the projectile to hit the planet is Imax = 2yR(1 + ER/Y),...

Find fn), if all circular orbits are to have identical areal velocities, A 2) For what values of n are circular orbits stable with the potential energy un-Ai where A > 0? 3) A satellite of mass m 2,000 kg is...
8.4 The Two-Dimensional Central-Force Problem The 2D harmonic oscillator is a 2D central force problem (as discussed in TZD Many physical systems involve a particle that moves under the influence of a central force; that is, a force that always points exactly toward, or away from, a force center O. In classical mechanics a famous example of a central force is the force of the sun on a planet. In atomic physics the most obvious example is the hydrogen atom,...
