# Shoot Him!

**Classical Mechanics**Level 3

Point A moves uniformly with a velocity **v** such that the vector **v** is continually aimed at point B which in turn moving straight and uniformly with velocity **u < v**. At the initial moment of time **v⊥u** and the points are separated by a distance *l*. How soon will the points converge?
