Answer:
D) The baby will continue to move forward as the car slows and be push into the padded car seat.
Explanation:
Newton's first law states that an object tends to be in a state of rest or motion unless and until an unbalanced external force acts on it. This means a body would continue to be in a state of motion unless external force stops it. A body in the state of rest will remain at rest unless an external force moves it.
An infant car seat is made to face the rear of the car. This is because, in case of a front-end collision, the car would come to a sudden stop but the bodies inside the car are in a state of motion and a sudden halt will cause the body to push in the opposite direction.
Thus, for an infant in the car, it would be a safer measure to place the seat facing the rear o the car because in this case, it would cause the baby to safely collide with the padded seat of the car.
