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.

Suppose you're riding your bicycle in the mountains. You climb a mountain pass on a scenic roadway and prepare to descend the other side of the mountains. You have a choice of two roads you can use to descend. One road is two miles long, while the other is ten miles long. Assuming you apply the same, consistent braking force throughout the duration of your descent for either route, which descent route will allow you to reach the base of the pass with the highest speed?
