Using the maximum principle we obtain the form ofoptimal control and establish conditions under which it contains a singularsubarc. This problem seems to be the simplest one having a mechanicalsense in which singular subarcs appear in a nontrivial way.Keywords: optimal control problem, Pontryagin Maximum Principle,extremals, singular arcs.2010 Mathematics Subject Classification: 49K15, 49N90.
