How does the total mechanical energy of the ball just before it reaches the ground (Ef) compare to Eo, the total mechanical energy just after it has been thrown? Ef < Eo because potential energy decreases Ef = Eo because the system is conservative Ef > Eo because kinetic energy increases There is no way to tell
