4. A mass m₁ = 2.10 kg travels upwards at a speed of 6.85 m/s when it collides with a mass m₂ = 3.65 kg that is initially at rest. After the collision, m, travels with a speed of 3.18 m/s in the direction of 34.0° from the vertical, as shown. Mass m₂ is observed to travel in the direction of 22.88° from the vertical. Vf.2 ? 3.18 m/s m₁ 22.880 m₂ 3.65 kg 34.0⁰ 6.85 m/s m₂ m₁ 2.10 kg a) What is the final speed of m₂? (20 points) b) Is this an elastic or inelastic collision? Show work to justify your answer.
