The figure above shows the path of a ball tossed from a building. Air resistance is ignored. a.
At what point of the ball's path shown in the figure above is the vertical component of the ball's velocity zero?
A
C. C
b. B
d. D

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.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
