The hoisting system shown is used to easily raise kayaks for overhead storage. Determine the velocity and acceleration of the kayak (positive if upward, negative if downward) when y = 73 in. if the winch Mreels in cable at the constant rate i = 8 in./sec. Assume that the kayak remains level. The distance b = 58 in.

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.
