Review | A 3.0-m-long steel chain is stretched out along the Part A Constants top level of a horizontal scaffold at a construction site, in such a way that 2.0 m of the chain remains on the top level and 1.0 m hangs vertically, the figure( How much work is performed on the chain by the force of gravity as the chain falls from the point where Figure 1) . At this point, the force on the hanging 2.0 m remains on the scaffold to the point where the entire chain has left the scaffold? (Assume that the segment is sufficient to pull the entire chain over the chain has a linear weight density of 19 N/m .) edge. Once the chain is moving, the kinetic friction is so small that it can be neglected . Express your answer using two significant figures.
