It is proven that for Newton-type problems the Pontryagin maximum principle is a necessary and sufficient condition. Solutions are then computed for concrete situations, including the new case when the flux of particles is non-parallel.Accepted for publication in the Rendiconti del Seminario Matematico dell'Universita e del Politecnico di TorinoOptimization and ControlMathematical Physics49K05; 70F35text
