The amount of work required to stretch 9 inches beyond the natural length will be 4.5 ft-lb
Given data:
To determine the work required to stretch the spring 9 inches beyond its natural length, use the concept of Hooke's Law.
Hooke's Law states that the force required to stretch or compress a spring is directly proportional to the displacement from its equilibrium position.
Given that stretching the spring by 2 ft requires 12 ft-lb of work, determine the constant of proportionality.
The constant of proportionality (k) represents the stiffness of the spring and can be calculated using the formula:
k = work / displacement
k = 12 ft-lb / 2 ft
k = 6 lb/ft
Now, calculate the work required to stretch the spring 9 inches (0.75 ft) beyond its natural length using the same constant of proportionality:
work = k * displacement
work = 6 lb/ft * 0.75 ft
work = 4.5 ft-lb
Hence, it would require 4.5 ft-lb of work to stretch the spring 9 inches beyond its natural length.

The first thing we must do for this case is to find the conversion of rupees to US dollars.
Currently, the conversion is:
1 rupee = 0.014 $
Then, to find the amount of $ in 2000 rupees, we make the following rule of three:
1 rupee -----------------> 0.014 $
2000 rupees ----------> x
From here, we clear the value of x.
We have then:
Answer:
2,000 rupees are 28 US dollars.
2,000 Indian Rupees is equivalent to 24 United States Dollars.
To convert 2,000 Indian Rupees to United States Dollars, you can multiply the amount in rupees by the conversion rate.
In this case, since 1 Indian Rupee equals 0.012 United States Dollars, the conversion can be calculated as follows:
2,000 Indian Rupees x 0.012 United States Dollars/Indian Rupee = 24 United States Dollars
Therefore, 2,000 Indian Rupees is equivalent to 24 United States Dollars.
