"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?)

For me It’s three because positive and you

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
