Answer:
50.0543248872 ft
Explanation:
F = Load = 20 ton = 
d = Diameter = 1.25 in
= Initial length = 50 ft
= Final length
A = Area = 
Y = Young's modulus = 
Young's modulus is given by
The length during the lift is 50.0543248872 ft
I believe the answer is H for when you bounce it, it has stress when it hits the floor and then goes up giving it kinetic
