A spool with an outer diameter of 8 cm descends by unwrapping an inextensible cable that is wound around a hub with a diameter of 4 cm. When the spool is rotating clockwise at w = 5 rad/s and accelerating clockwise at a = 6 rad/s2, find the linear accelerations at point A and point B. a. Point A accelerates at 110 o cm/s? b. Point B accelerates at 91 v o cm/s2 Round all answers to 2 significant figures.

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.
