A. The friction applied by the table to the cue ball.
B. The force applied by the stick to the cue ball
C. The force exerted by the black ball to the cue ball.
D. the force of gravity on the cue ball

Anyway, given the principal that energy cannot be created or destroyed, the kinetic energy from the swing of the cue (which the OP calls the 'stick') is transferred from the tip of the cue to the cue ball, with part of it lost as the ball travels across the baize, until the cue hits the target ball. At this point, the energy is dissipated according to the left-hand rule and the resultant resting position defined by subtracting nines according to the law of overhead underhang.
