Point A moves uniformly with velocity v so that the vector v is continually aimed at point B which in its turn moves recti- linearly and uniformly with velocity u < v. At the initial moment of time v is perpendicular to u and the points are separated by a distance l . How soon will the points converge?

The separation between A and B reduces uniformly at dr/dt=lv-ul
therefore, answer=l/(v-u)
