A car is parked in its driveway facing away from the street. Its owner backs the car out onto the street. As the car starts from rest and gains speed up to 5 mph backing out of the driveway, its 1. velocity points toward the front of the car, while its acceleration points toward its rear. 2. velocity points toward the rear of the car, and its acceleration is zero. 3. velocity points toward the rear of the car, and its acceleration points toward its rear. 4. velocity points toward the rear of the car, while its acceleration points toward its front. 5. velocity points toward the front of the car, and its acceleration points toward its front.

3. velocity points toward the rear of the car, and its acceleration points toward its rear

Explanation:

If a car is parked facing away from the street and then the car is backed out on the street from rest to 5 miles per hour. The acceleration in this case points in the backward direction because the car speeds up in the rear direction and the motion of the car is also in the backward direction since the velocity of the car is rearward.

Here the acceleration cannot be zero because the velocity of the car changes with time.
