Problem
A projectile is fired horizontally from the top of a cliff at the same instant that an identical object is simply dropped from the same height. Ignore air resistance. Which statement best describes when the two objects reach the ground?
(a) The fired projectile lands first because its initial horizontal speed is greater.
(b) They land at the same time because their vertical motions are identical.
(c) The fired projectile lands later because it has to travel a longer path through space before reaching the ground.
(d) The fired projectile lands first only if its horizontal speed exceeds a certain threshold.
