Abstract
An old problem of finding
the curve
of pursuit and the point of intersection, originally proposed by
Leonardo
da Vinci, is considered in its generality. It is assumed that the
pursued
moves along an arbitrary straight line and the motion of the pursuer is
always directed towards the pursued. Both the pursuer and the pursued
move
at constant but arbitrarily different speeds. A novel and elegant
scheme
of calculation is devised here by which the point of intersection can
be
calculated very simply without any explicit determination of the
trajectory
of the pursuer. Then the scheme is extended to give the analytical
expressions
for the actual curve of pursuit. The present method of solution is more
general and very considerably simpler than existing solution
techniques.
Some physics of the problem is discussed..
