A 30-m long chain hangs vertically from a cylinder attached to a winch, and a 50-kg block is attached to the end of the chain. Assume there is no friction in the system and that the chain has a density of 5 kg/m. How much work is required to wind the chain onto the cylinder?

the answer is c. hope this !

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
