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.

Question

Q1: The cars A and B are traveling with the
velocities shown when they collide. Assuming the
impact is plastic, determine: (a) the common
velocity of the cars just after the impact; and (b) the
percentage of mechanical energy absorbed by the
impact.
