a) Calculate the maximum value of b for which the rope will not start sliding down the slope. Assume that b= 0.18 m and that the coefficient of kinetic friction between the rope and the inclined surface is k = 0.36. Let y (in metres) be the distance travelled by the rope after it has been released from rest. b) Calculate the initial acceleration of the rope. c) Calculate the work done by gravity as a function of y.

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.
