#Problem

Hey I wondered how we can find the intersection between a point with a vector direction, assuming that the point is in the circle.

In Other words, how can I find where the particle will hit the circle circumference when I know the following: Circle position, radius, Particle Position and direction (velocity).

#Implementation

I am currently creating a flight radar, all flights are stored in a Queue and I need to sort the queue based on the time untill the flight leaves the cirlce (Radar Radius)

So I need to return a Point, thus I can just get the distance and calculate the time based on distance and velocity.
