To transport a series of bundles of shingles A to a roof, a contractor uses a motor-driven lift consisting of a horizontal platform BC which rides on rails attached to the sides of a ladder. The lift starts from rest and initially moves with a constant acceleration a(1) as shown. Knowing that the coefficient of static friction between a bundle of shingles and the horizontal platform is 0.25 , determine the largest allowable acceleration a(1) , if the bundle i, NOT to slide on the platform.

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.
