Rotational or Angular Motion
... The net torque now adds to zero—and the board does not rotate. The board is in rotational equilibrium. Note: This will only be true if the board is uniform and the pivot is at the center of the board, so that the gravitational force is causing no torque on the board. ...

(e) None of the above
... (b) The impacts will be equal since each has a weight of zero in space. (c) The bullet will hurt more since it's smaller and therefore has more acceleration. (d) The impacts cannot be compared since exact masses and velocities are not known. (e) None of the above are true. ...
