Answer:
D) Moving the book to a higher shelf.
Explanation:
more height
speed is the same because of gravity
Increase falling book speed.
Answer: Moving the book to a higher shelf.
Moving the book to a higher shelf would increase the maximum potential energy of the book.
This increase in potential energy would result in a higher velocity as the book falls due to the conservation of energy principle.
Adding pages to the book or ripping pages out of the book would not affect the maximum speed of the falling book.
The formula for potential energy is PE = mgh, where m is the mass of the book, g is the acceleration due to gravity, and h is the height of the shelf.
The maximum speed of the falling book can be calculated using the formula v = sqrt(2gh), where v is the velocity of the falling book.
Analogy: Just like a person sliding down a slide would gain more speed if they start from a higher point, a book falling from a higher shelf will also gain more speed than one falling from a lower shelf.
Summary: Moving the book to a higher shelf would increase the maximum speed of the falling book.
Math:
PE = mgh
v = sqrt(2gh)
In the equations PE = mgh and v = sqrt(2gh):
P represents potential energy, measured in joules (J).
m represents the mass of the object, measured in kilograms (kg).
g represents the acceleration due to gravity, which is approximately 9.8 meters per second squared (m/s^2) on Earth.
h represents the height of the object above a reference point, measured in meters (m).
v represents the velocity of the object, measured in meters per second (m/s).
