Document Summary
Fall 2006: death star (20 pt) a particle of mass m is subject to a central force given by the potential. If the particle gets over the peak of the potential it will spiral into the star. So we need to find the maximum energy it can have before reaching the top, which is equal to. The angular momentum is related to the impact parameter and the velocity at infinity l. The total cross-section is the area that would be swept out by the star if a uniform stream of particles was impinging on it: b tot. The solution has to satisfy the wave equation, it can be written as txy. , where a, b and are arbitrary cos( sin( sin( kx kx. A t constants and k and are related by k = /v, where v. Mgl m: what are the boundary condition on y(x,t) at x = 0 and x = l ? l.
