Mary throws a baseball straight upward. We can ignore air resistance. What is true about the acceleration and velocity of the ball on its way down

Correct option is A.

Explanation:

Given that baseball is launched direct skyward.

Now acceleration on the ball will forever remain consistent and will be equivalent to the acceleration due to gravitation. (g = -9.8 m/s^2)

Now given that the skyward direction is positive, So as baseball travels skyward since acceleration is earthward, So the velocity of baseball will decline, and at the top-point velocity enhances zero.

Now during earthward motion since acceleration is earthward, and the ball is also traveling earthward, So the velocity of baseball will expand. But since the earthward direction is negative, So speed will improve negatively.

This means Velocity drops.
