The same net external force is applied first to a basketball and then to a stalled car. What happens to the acceleration?

1. Acceleration is inversely proportional to the mass of the system. 2. The larger the mass, the smaller the acceleration produced by a given force. 3. A car has far more mass than a basketball, so it accelerates far less under the same push. 4. The free-body diagrams are identical, so only the mass explains the difference. 5. The car does accelerate, just by an amount too small to notice. _Source: OpenStax College Physics (CC BY 4.0), Ch 4 "Dynamics: Force and Newton's Laws of Motion", section 4.3 Newton's Second Law of Motion: Concept of a System_
