## Homework Statement

A particle is traveling with a constant velocity v along a line that is a distance b from the origin O. Let dA be the are swept out by the position vector from O to the particle in time dt. Show that dA/dt is constant in time and equal to (1/2)*L/m, where L is the angular momentum of the particle about the origin.

## Homework Equations

L= rmv
