5. A softball player catches a ball of mass m , which is moving towards her with horizontal speed V . While bringing the ball to rest, her hand moved back a distance d. Assuming constant deceleration, the horizontal force exerted on the ball by the hand is (A) mV2/(2 d)\mathrm{mV}^{2} /(2 \mathrm{~d}) (B) mV2/dm V^{2} / d (C) 2mV/d2 \mathrm{mV} / \mathrm{d} (D) mV/d\mathrm{mV} / \mathrm{d}
