Answer:
B. B
Explanation:
The picture shows a projectile launched, the vertical component of the ball's Velocity will be zero at it's point of maximum height. The point of maximum height in th diagram is the point marked B. At this point, there is a change in the direction of the object's motion, as it begins to accelerate downward. This change in direction of object's motion will occur at the maximum height of the launched object and thus the Velocity at the point will be equal to zero.
