11 / 11 1 - 61% + Problem 10. [16 pts] A chain lying on the ground is 10 m long and its mass is 80 kg. One end of the chain is raised to a height of 6 m. (a) Draw "before" and "after" pictures of this scenario. That is, draw one picture of the chain lying on the ground. Then, draw a second picture of the chain with one end raised to a height of 6 m. Choose where dy (a tiny portion of the chain) should be, and clearly label dy on both pictures. Also, clearly label distance y in your "after" picture. (b) How much work (in J) is required to raise one end of the chain to a height of 6 m? Use 9.8 m/s2 for the value of g. Start by developing an expression for dWork, then integrate it to find Work
