(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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.

2. Relevant equations

L= rmv

3. The attempt at a solution

Any hint on how to do this problem ???
