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

3/81 The slotted arm revolves in the horizontal plane
about the fixed vertical axis through point O. The
2-kg slider C is drawn toward O at the constant rate
of 50 mm/s by pulling the cord S. At the instant for
which r = 225 mm, the arm has a counterclockwise
angular velocity w = 6 rad/s and is slowing down at
the rate of 2 rad/s2. For this instant, determine the
tension T in the cord and the magnitude N of the
force exerted on the slider by the sides of the smooth
radial slot. Indicate which side, A or B, of the slot
contacts the slider.
