Question

a book is dropped and falls to the floor. which of the following describes the forces between the book and the floor when the book hits the floor? the book does not exert a force on the floor, but the floor exerts a force on the book. the force exerted by the book on the floor is greater in magnitude than the force exerted by the floor on the the book exerts a force on the floor, but the floor does not exert a force on the book. the force exerted by the book on the floor is equal in magnitude to the force exerted by the floor on the

Explanation:

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When the book hits the floor, the book exerts a force on the floor (action), and the floor exerts an equal - magnitude force on the book (reaction).

Answer:

The force exerted by the book on the floor is equal in magnitude to the force exerted by the floor on the book.
