Please explain thoroughly using conservation of energy principles and explain the why to each step. I am really struggling here. Thanks!
l. Two blocks are attached by light wires in the configuration shown in the figure below. The block B of mass 70.0 kg rests on a wedge platform fixed to the floor, and the static coefficient of friction between the block and the wedge surface is 0.24. Find the maximum mass of block A for which the block B will remain at rest.
