A ball is projected horizontally from the top of a building. One second later, another ball is projected horizontally from the same point with the same velocity (a) At what point in the motion will the balls be closest to each other ? (b) Will the first ball always be traveling faster than the second ? (c) What will be the time difference between them when the balls hit the ground ? (d) Can the horizontal projection velocity of the second ball be changed so that the balls arrive at the ground at the same time?
