Suppose you throw a ball vertically downward with an initial speed of 15 m/s. Neglecting air friction, what would be the speed of the ball one second later? Here, the vertically pointing down acceleration of gravity has the positive sign along with the positive vertically down of the frame of reference, with magnitude g = + 9.8 m/s² A. -9.8 m/s². B. 9.8 m/s². C. 5.2 m/s. D. 15 m/s. E. 24.8 m/s.
