A body of mass 1.0 kg moves in X-Y plane under the influence of a conservative force. Its potential energy is given by $$U = 2x + 3y$$ where $$(x, y)$$ denote the coordinates of the body. The body is at rest at $$(2, -4)$$ initially. All the quantities have SI units. Therefore, the body

A

moves along a parabolic path.

B

moves with a constant acceleration.

C

never crosses the X axis.

D

has a speed of $$2\sqrt{13}$$ m/s at time $$t = 2$$ s.
