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

The disk rotates about a fixed axis through point O with a clockwise angular velocity wo = 17 rad/s and a counterclockwise angular
acceleration ao = 5.1 rad/s? at the instant under consideration. The value of r is 250 mm. Pin A is fixed to the disk but slides freely
within the slotted member BC. Determine the velocity and acceleration of A relative to slotted member BC and the angular velocity
and angular acceleration of BC. The relative velocity and acceleration are positive if they point from B to C and negative if they point
from C to B. The angluar velocity and angular accelerations are positive if counterclockwise, negative if clockwise.
