An object of unknown mass is initially at rest and dropped from a height h. It reaches the ground with a velocity v1 v 1 . The same object is then raised again to the same height h but this time is thrown downward with velocity v1 v 1 . It now reaches the ground with a new velocity v2 v 2 . How is v2 v 2 related to v1 v 1 ?
