The final linear momentum (in the x, y or z direction) is equal to :

a) the sum of the initial linear momentum and the momentum of the force in that same direction. b) the sum of the initial energy and the work of the force in a perpendicular direction. c) the sum of the initial energy and the work of the force in the same direction. d)the sum of the initial linear momentum and the momentum of the force in a perpendicular direction.
