Point A moves uniformly with velocity v so that the vector v is continually “aimed” at point B which in its turn moves rectilinearly and uniformly with velocity u At the initial moment of time v perpendicular to u and the points are separated by a distance L. How soon will the points converge?
Express the position vector rAB in Cartesianvector form, then determine its magnitude and coordinatedirection angles.
Derive expressions for the velocity (~v) and acceleration (~a) vectors in spherical coordinates.That is, transform ~v and ~a from the Cartesian system of (x, y, z) to (r, θ, φ).

In this way, in order to carry out an analytical study of its motion in a simpler way, consider a coordinate system xoy, with its origin at the particle's launch position, and with its positive x axis oriented in the direction of the horizontal motion of the particle and with its positive y-axis oriented vertically upward.
