Problem
A projectile is launched from the top of a high cliff and lands on valley floor that is lower than the launch point. Neglect air resistance. Which of the following best describes the comparison between the time the projectile spends ascending to its maximum height and the time it spends descending from that point to the valley floor?
(a) The descent time is greater than the ascent time.
(b) The ascent time equals the descent time.
(c) The ascent time is greater than the descent time.
(d) The relationship cannot be determined without knowing the launch angle.
