Answer: Velocity is zero, Acceleration is negative
Explanation:
This situation describes the parabolic movement, when the object is shot vertically upwards its velocity is positive, while the acceleration due to gravity will always be negative (because its direction is in the direction of the center of the Earth); until the object reaches its maximum height where the speed is zero and then it begins to fall until it hits the ground.
Therefore, the answer is:
Velocity is zero, acceleration is negative
