e)? View Available Hint(s) Which ball has the greater average speed during the 1-s interval after release (assuming neither hits the ground during that time)? the ball thrown upward the ball thrown downward Neither; the average speeds of both balls are the same.
When the ball is thrown vertically, the acceleration of it is the gravity acceleration independent if it is thrown downward or upward. However, the acceleration is a vector, so, when the ball is thrown upward, the movement is against the gravity, so the acceleration is negative, and so, the velocity decreases during time; and when the ball is thrown downward, the movement goes to the gravity, so the acceleration is positive, so the velocity increase after time passes.
