A person pushes horizontally with constant force P on a 230 N box resting on a frictionless horizontal floor.
Which of the following statements about this box is correct?
A.The box will accelerate no matter how small P is.
B. The box will not accelerate unless P > 230 N.
C. The box will move with constant velocity because P is constant.
D.Once the box is set moving, it will come to rest after P is removed.

A. Because on a fricitionless horizontal surface any finite mass will accelerate if any finite net force is applied in any direction that is not perpendicular to the said surface.
