Answer:
Its velocity along the y axis is zero. Which statement is true if an object undergoing free fall reaches its maximum height? Its acceleration is zero.

Answer:
Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
[Is gravitational acceleration really constant?]
For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration ggg, the magnitude of velocity decreases as the ball approaches maximum height.
