Final answer:
The horizontal component of the ball's velocity remains constant at 24 m/s after 2 seconds since air resistance is negligible.
Step-by-step explanation:
The student is asking about the behavior of a ball thrown horizontally with a specific initial velocity, in the absence of air resistance. The horizontal component of the ball's velocity remains constant at 24 m/s after 2 seconds since air resistance is negligible.
When we assume that air resistance is negligible, the horizontal component of the velocity remains constant because there are no horizontal forces acting on the ball. Therefore, the horizontal component of the ball's velocity after 2 seconds would still be 24 m/s.
