This review explores the principles of momentum conservation through a detailed analysis of two boxcars in an inelastic collision. The first boxcar, with a mass of 2000kg, is moving to the right at 3 m/s, while the second boxcar, weighing 3000kg, moves to the left at 1 m/s. When they collide and couple together, we will calculate their final speed using the conservation of momentum. The review also covers essential concepts in thermal physics, such as internal energy, temperature, heat flow, and latent heat, providing valuable insights into momentum and energy transfer.

Test Review Starter A 2000kg boxcar moving to the right at 3 m/s runs into a 3000kg boxcar moving to the left at 1m/s. What is the speed of the boxcars after they couple together? Conservation of Momentum
