A particle is projected vertically upward from the Earth’s surface with speed greater than the escape speed. Neglecting air resistance, which statement about its total mechanical energy E and the nature of its orbit is correct?
(a) E is zero; the particle follows a parabolic path.
(b) E is negative; the particle follows an elliptical path.
(c) E is positive; the particle follows a hyperbolic path.
(d) E is positive; the particle follows a parabolic path.
