Freight car A with a gross weight of 155000 lb is moving along the horizontal track in a switching yard at 2.4 mi/hr. Freight car B with a gross weight of 145000 lb and moving at 3.6 mi/hr overtakes car A and is coupled to it. Determine (a) the common velocity V of the two cars as they move together after being coupled and (b) the loss of energy |ΔE| due to the impact.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
