When a car suddenly stops at a red light, a book lying on the car seat slides forward. Why does the book continue to move forward? A: The car moves in reverse more rapidly than the book.
B: The friction of braking transfers energy to the book
C: The book’s inertia causes it to continue moving

C

Explanation:

The answer is c because Newton’s third law states “ for every action there is an equal and opposite reaction.” Since the car quit moving the book did not stay at rest because there was a reaction.

C

Explanation:

Newton's 1st law of motions states : " Intertia: A objects resistance to change. More mass= more intertia. Less mass= Less intertia.

it ALSO states that an object at rest will stay at rest, until an outside forces acts upon the object, forming an unbalanced force.  

The car stopping suddenly is the outside force, and the book sliding forward is the intertia to change.
