A person standing near the edge of the top of a building throws two balls A and B. The ball A is thrown vertically upward and B is thrown vertically downward with the same speed. The ball A hits the ground with a speed vA and the ball B hits the ground with a speed vB. We have:
  1. vA > vB
  2. vA < vB
  3. vA = vB
  4. The relation between vA and vB depends on height of the building above the ground.
