Answer:Adding mass to a car will not increase the average speed of the car. In fact, it will have the opposite effect and decrease the average speed
Step-by-step explanation:
To understand why this happens, we need to consider Newton's second law of motion. This law states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. In simpler terms, the more mass an object has, the more force is required to move it. When a car is moving, it experiences various forces such as friction and air resistance. These forces act against the car's motion and must be overcome by the engine to maintain or increase its speed. By adding mass to the car, we are increasing the total mass that needs to be moved. This means that the engine will have to exert more force to overcome the increased inertia and move the car. As a result, the car's acceleration will be slower, and it will take longer to reach a certain speed. This ultimately leads to a decrease in the car's average speed.
