We numerically simulate the motion of a black hole as it plunges radially through an ultralight dark matter (ULDM) soliton. We investigate the timescale in which dynamical friction reduces the kinetic energy of the black hole to a minimum and consider the sensitivity of this timescale to changes in the ULDM particle mass, the total soliton mass, and the mass of the black hole.
