A 10,000-kg railroad car, A, traveling at a speed of 24.0 m/s strikes an identical car, B, at rest. If the cars lock together as a result of the collision, what is their common speed just afterward?In Example #1 (linear momentum lecture), a railroad car, A, traveling at a speed of 24.0 m/s strikes a car, B, at rest. The cars lock together as a result of the collision. What is their common speed just afterwards if (a) mB = 3mA, (b) mB is much larger than mA (mB>>mA), and (c) mA>>mB?

Question

A 10,000-kg railroad car, A, traveling at a speed of 24.0 m/s strikes an identical car, B, at rest. If the cars lock together as a result of the collision, what is their common speed just afterward?

In Example #1 (linear momentum lecture), a railroad car, A, traveling at a speed of 24.0 m/s strikes a car, B, at rest. The cars lock together as a result of the collision. What is their common speed just afterwards if (a) m_B = 3m_A, (b) m_B is much larger than m_A (m_B>>m_A), and (c) m_A>>m_B?
