We study motion of particles and light in a space-time of a 5-dimensionalrotating black hole. We demonstrate that the Myers-Perry metric describing sucha black hole in addition to three Killing vectors possesses also a Killingtensor. As a result, the Hamilton-Jacobi equations of motion allow a separationof variables. Using first integrals we present the equations of motion in thefirst-order form. We describe different types of motion of particles and lightand study some interesting special cases. We proved that there are no stablecircular orbits in equatorial planes in the background of this metric.Comment: Added discussion about (non)existence of stable circular orbits.  Accepted for publication in Phys. Rev.
