Answer:
Work done will be equal to 5.2059 lb-ft
Step-by-step explanation:
We have given force F = 10 lb
Spring is stretched to 2 in
So x = 2 in
As 1 inch = 0.0833 feet
So 2 inch = 2×0.0833 = 0.1666 feet
From hook's law we know that F = Kx , here K is spring constant and x is spring elongation
So
K = 60.024 lb/feet
Now new elongation x = 5 in
So 5 in = 5×0.0833 = 0.4165 feet
Work done is given by
So
So work done will be equal to 5.2059 lb-ft

<h2>Explanation:</h2>
Here we have a line given by the equation:
This line is given in Slope-intercept form, recall that this form is as follows:
So in this case:
So a point that lies on the line is:
Another point would be:
So the line must pass through these two points. By using graphing tool we get the line shown below.
