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.

checkpoint, and the specified time between points A and B is 10 min
20 s. Knowing that the driver accelerates and decelerates at the same
constant rate, determine the magnitude of her acceleration if she trav-
