It uses arrows to show what way the wind is going
Answer:
(5) It depends on whether the collision was elastic or inelastic.
Explanation:
Due to the absence of external forces and the fact that masses and initial velocities are known, it is needed to determine if collision is elastic or inelastic. If collision is inelastic, the Momentum Principle is sufficient to calculate final momentum, but if it is elastic, the Momentum Principle should be complemented with the application of the Energy Principle.
Hence, the correct answer is (5).
