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

Magnetic tape is being transferred from reel A to reel B and passes around idler pulleys Cand D. At a certain instant, point
