Mechanical energy problem 4 part 2

The video tutorial revisits a problem involving two blocks connected by a rope, focusing on the forces acting on them as they move. It explains the concept of mechanical energy and the role of nonconservative forces like friction and normal force. The tutorial calculates the work done by these forces and discusses the change in mechanical energy of the system. It also analyzes the normal force using a free body diagram, emphasizing the importance of understanding force components and their directions.

Discuss the implications of the normal force being perpendicular to the path of the block.
