Let \(H^3\) be the upper sheet of the hyperboloid embedded into Minkowski space. In this paper, the author proves the integrability of Euler and Lagrange problems in the space \(H^3\). The classification of the domains of possible motion on the pseudosphere, which allows to answer the question about the trajectory equivalence of Euler and Lagrange problems in planar and curved spaces, is carried out. Additionally, the author investigates the influence of the space curvature on the integrability of the equations of motion of a point mass in a constant curvature space.
