When a car is traveling north at a constant speed and a force is applied directly east, the car's speed will remain the same because the force is not acting in the direction of motion (north). However, the applied force will cause the car to change direction.

Therefore, the correct response is:

D. The speed will remain the same, but the car will change the direction it is moving.
