The claim about the forces acting on the car that must be true in this situation is:
1. There is a net force on the car.
Explanation:
- When the car is stopped at a red light, it is not in motion, which means the forces acting on it are in equilibrium.
- Even though the car is not moving, there are still forces acting on it, such as gravity pulling it down and the normal force from the ground pushing it up.
- In this case, the net force on the car is zero because the forces are balanced, resulting in no acceleration or movement of the car.
- Therefore, the correct claim is that there is a net force on the car, which is equal to zero in this stationary situation.
