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
Newton's third law says:
"<span>For every action, there is an equal and opposite reaction. ".
So, the force that Tom does on the sister is equal to force the sister applies on Tom:
</span>
<span>where the label "t" means "on Tom", while the label "s" means "on the sister".
From Newton's second law, we also know
</span>
where m is the mass and a the acceleration. <span>so we can rewrite the first equation as
</span>
<span>And find Tom's acceleration:
</span>
