"Nate throws a ball straight downward, letting it bounce once before catching it. (we can ignore air resistance) A. what is true about the acceleration AND the velocity of the ball on its way down?
(assume upward is a positive direction)
1. Acceleration increases and velocity is negative and thus decreasing
2. Acceleration remains constant and velocity is negative and thus decreasing
3.Acceleration is decreases and velocity is positive and increasing
4. Acceleration remains constant and velocity is negative and decreasing

(What of the four suggestions is correct?)
