Two balls are thrown from the top of a building. Ball 1 is thrownstraight down, and ball 2 is thrown with the same speed, but upwardat an angle theta with respect to the horizontal. Consider themotion of the balls after they are released. Which one of thefollowing statements is true?
A.) The acceleration of Ball 2 decreases as it rises, becomes zeroat the top of the trajectory, and then increases as the ball beginsto fall toward the ground.
B.) Both balls have the same acceleration at all times.
C.) Ball 2 has an acceleration in both the horizontal and verticaldirections, but Ball 1 has an acceleration only in the verticaldirection.
D.) The acceleration of Ball 1 becomes larger as it falls, becausethe ball is going faster and faster
The answer is not C**
