Atarget in a shooting gallery consists of a vertical square wooden board, 0.210 m on a side and with mass 0.730 kg , that pivots on a horizontal axis along its top edge. the board is struck face-on at its center by a bullet with mass 2.00 g that is traveling at 315 m/s and that remains embedded in the board. what minimum bullet speed would be required for the board to swing all the way over after impact?
