Answer:
Option b. it has the same position and the same acceleration as A
Explanation:
Let's analyze every statement:
a. it has the same position and the same velocity as A
In the instant where B passes A, they Do have the same position. Velocity however, cannot be the same because if they were, ball B would never pass ball A. So, this is false.
b. it has the same position and the same acceleration as A
As we said in the previous option, the position is the same. The acceleration is gravity for both balls, so this is true.
c. it has the same velocity and the same acceleration as A
Acceleration is the same but velocities are not, so this is false.
d. it has the same displacement and the same velocity as A
The distance they have traveled is the same, so the displacement is the same, but the velocity is not, so this is false.
e. it has the same position, displacement and velocity as A
The position and displacement is the same but not velocity, so this is false.
Only option b is true.
