Three blocks of masses m1=1.00 kg, m2=2.00 kg, and m3=3.00 kg are set at rest on a level air track from right to left. Then m3 is pushed toward m2 with a speed of 3.00 m/s. Assuming that all collisions are elastic, what are the final speeds of (a) m1, (b) m2, and (c) m3?

Question
Three blocks of masses m1=1.00 kg, m2=2.00 kg, and m3=3.00 kg are set at rest on a level air track from right to left. Then m3 is pushed toward m2 with a speed of 3.00 m/s. Assuming that all collisions are elastic, what are the final speeds of (a) m1, (b) m2, and (c) m3?
Transcribed Image Text:**Problem Description:**
Three blocks of masses \( m_1 = 1.00 \, \text{kg} \), \( m_2 = 2.00 \, \text{kg} \), and \( m_3 = 3.00 \, \text{kg} \) are set at rest on a level air track from right to left. Then \( m_3 \) is pushed toward \( m_2 \) with a speed of \( 3.00 \, \text{m/s} \). Assuming that all collisions are elastic, what are the final speeds of (a) \( m_1 \), (b) \( m_2 \), and (c) \( m_3 \)?
**Options:**
(a) \( m_1 \): 0.6 m/s ❌
(b) \( m_2 \): 1.2 m/s ✔️
(c) \( m_3 \): 4.8 m/s ❌
**Explanation:**
In this setup, due to the conservation of momentum and the assumption of elastic collisions, specific calculations can be performed to determine the final speeds of each block after the collision sequence. The problem provides options, and the correct answer for \( m_2 \) is highlighted with a check mark.
