Q1. An apple is dropped from a cliff. Another apple is thrown upward from the same position.

1. When they reach the ground at the bottom of the cliff, which apple has a greater velocity? The apple thrown upward.
2. Which has a greater acceleration?
3. Which arrives first? The apple that is dropped.

Q2. Presume that you loft the ball with the initial speed of v = 17.6m/s, at an angle of θ = 50.7° above the horizontal. At this instant your opponent is d = 11.19m away from the ball. He begins moving away from you 0.35s later, hoping to reach the ball and hit it back at the moment that it is h = 2.15m above its launch point. With what minimum average speed should he move? (Overlook the fact that he can stretch, so that his racket can reach the ball before he does.)
