Problem
14 In the absence of air friction, an object dropped near the surface of the Earth experiences a constant acceleration of about 9.8m/s2. This means that the
(A) speed of the object increases 9.8m/s during each second
(B) speed of the object as it falls is 9.8m/s
(C) object falls 9.8 meters during each second
(D) object falls 9.8 meters during the first second only
(E) derivative of the distance with respect to time for the object equals 9.8m/s2
