Question

If a car is going 25 mph on the street and suddenly stops, a book on the seat flies off of the seat and hits the floor. Why did the book continue to move after the car stopped?A. The book should not have moved from the seat.B. The book did not obey Newton's Laws.C. The car should have continued to move after the brake was applied and the book should have remained on the seat.D. The car stopped, however because of the law of inertia the book continued to move.

Answer 1

Given:

The initial speed of the car is,

`v_i=25\text{ mph}`

When suddenly the car stops a book on the seat flies off of the seat and hits the floor.

To find:

The reason

Step-by-step explanation:

The car was initially moving at a certain speed so the book on the car seat was moving with the car at the same speed.

After the car stopped, the book tries to continue the inertia of motion as per Newton's first law, so the book continues to move after the car stops.

Hence, the car stopped, however, because of the law of inertia the book continued to move
