Answer: The book hits first
Explanation:
In the video Dr. Hewitt drops 3 objects from a certain height. The object are books and paper.
The books will hit the ground first because it is heavy and the gravity will act more on the book as compared to the paper.
The paper will face more resistance of air as compared to that of book so it will take time to reach the ground.
Hence, the correct answer is that the book will hit the ground first in the video.
