Intersection of vector and triangle side

virusys

1. The problem statement, all variables and given/known data

I have a triangle with given vertices ABC. Given a vector that starts from A and intersects side BC, how can I find the point of intersection, p?

Thanks

2. Relevant equations

3. The attempt at a solution
