Randomized Variables m 61 kg d = 0.78 cm l=39 m G> By how mulch does the mountain climler stretch her rope, m centimeters, when she hangs 39 m below a rock outcropping? Assume the Young's modulus of the rope is 5 109 N/m2 Grade Summary Potential 100% sind) cos() tanQ ()171 cotanasinacos atan acotasinho cosh0h colanh Submissions Allrts ng: (10 per attempt) detailed view Dcgrces Radians NO Subrnit Hint I give up! Hints: 0% deduction per hint. Hinter emaining: 3 Feedback: 196 deduction per feedback.Explanation / Answer
change in length of the rope = F L / Y A
= (m g L) / (Y *pi * r2)
= (61 * 9.8 * 39 ) / ( 5 x 109 * 3.14 * 0.392 x 10-4)
= 0.098 m = 9.80 cm
