Question

a chain is held on a frictionless table with 1/3 of its length hanging over the edge. If the chain has length L = 25 cm and mass m = 34 g, how much work is required to pull the hanging part back onto the table?

Answer 1

\[\huge \int\limits_{0}^{\frac{.25 }{ 3}}\frac{ .034 }{ .25}*g*y dy\]

Answer 2

the answer suppose to be in Newtons

Answer 3

it is.

Answer 4

see the meters and kg in that equation?

Answer 5

No, if the answer is the work needed, the answer must be in joules, not in newtons.

Answer 6

I think he meant newton meters. but whatever.
