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.

Korean Bell. A bell-ringer hits a massive bell using a 21-kg cylindrical log. The log is supported by two cords that behave like a rod. He normally uses a 200-N force P, at 60° with respect
to the log, to push the log towards the bell. Assuming the two supports have negligible mass, determine the (a) normal and tangential accelerations of the log, and the (b) force developed at each support, at the instant when the cords are vertical and the angular velocity of the log is ω = 6 rad/s, CW.
