We present dynamical modeling of the broad line region (BLR) in the Seyfert 1 galaxy Mrk 50, using reverberation mapping data taken as part of the Lick AGN Monitoring Project 2011. We model the reverberation mapping data directly, constraining the geometry and kinematics of the BLR, as well as deriving a black hole mass estimate that does not depend on a normalizing factor or virial coefficient. We find that the geometry of the BLR in Mrk 50 is a nearly face-on thick disk, with a mean radius of 10 light days. We also constrain the inclination angle to be 80 degrees, closer to face-on. Finally, we measure the black hole mass to a precision of 0.4 dex. We compare our inferred black hole mass to the virial black hole mass, Mvir = (f v2 c tau)/G, measured from traditional reverberation mapping analysis, also constraining the normalizing coefficient, f, to within 0.4 dex. While our dynamical model includes the possibility of a net inflow or outflow in the BLR, we find a slight preference for outflow.
