8. In Scenario I, two air carts have the same mass and are moving in the same direction at the same speed. In Scenario 11, two air carts have the same mass and are moving in the opposite direction at the same speed. The masses and speeds in Scenario I and Il may not be the same. Considering the two air carts in each Scenario to be a system. which of the following statements must be true. A) The magnitude of the total momentum in Scenario I is larger than the magnitude of the total momentum of Scenario II. B) The magnitude of the total momentum in Scenario I is smaller than the magnitude of the total momentum of Scenario 1]. C) The magnitudes of the total momentum in Scenario I is the same as the magnitude of the total momentum of Scenario II. D) One would need the mass and velocities to determine which of the statements above are true. 9. A satellite is orbiting Earth with a period of 16 hours.
