16. A group of students conducts an experiment in which two carts collide with each other as they travel across a horizontal surface with negligible friction. Using motion detectors and a mass balance, the students collect data about the carts immediately before and immediately after the collision, as shown in the table below. Which of the following claims is true regarding the momentum and the kinetic energy of the two-cart system for the experiment? Does the data indicate that a net external force acts on the system? 1.0 Cart 1 mass (kg) Cart 2 mass (kg) 2.0 Velocity of Cart 1 prior to collision 4.0 Velocity of Cart 2 prior to collision 0. Velocity of Cart 1 after the collision 1.0 Velocity of Cart 2 after the collision 1.0 A. The momentum is the same and the total kinetic energy of the system is different immediately before the collision and immediately after the collision. This indicates that a net external force is not exerted on the system. B. The momentum is the same and the total kinetic energy of the system is different immediately before the collision and immediately after the collision. This indicates that a net external force is exerted on the system. C. The momentum is different and the total kinetic energy of the system is the same immediately before the collision and immediately after the collision. This indicates that a net external force is not exerted on the system. D. The momentum is different and the total kinetic energy of the system is different immediately before the collision and immediately after the collision. This indicates that a net external force is exerted on the system.
