PROBLEM 11.161 The oscillation of rod OA about O is defined by the relation 0= (2/T) (sin rT), where e and t are expressed in radians and seconds, respectively. Collar B slides along the rod so that its distance from O is r = 625/(t+4) where r and t are expressed in mm and seconds, respectively. When t= 1 s, determine (a) the velocity of the collar, (b) the total acceleration of the collar, (c) the acceleration of the collar relative to the rod. B

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.
