Step 1
Which ONE of the following statements about the forces acting on the car is CORRECT?
Answer
To determine the correct statement regarding the forces acting on the car, we must first recall the concept of forces in equilibrium. If a car is moving at a constant velocity, according to Newton's first law of motion, the net force acting on it must be zero. This means that all forces are balanced, and therefore, the weight of the car and the normal force must be equal. Hence, the statement 'The net force acting on the car is zero' is correct.
Thus, the answer is: A. The net force acting on the car is zero.
