the spring by moving one end 5.31 cm from
its unstressed position.

To find the force constant of the spring, we can use Hooke's Law, which states that the force required to stretch or compress a spring is directly proportional to the displacement from its equilibrium position.
Hooke's Law can be written as:
F = k * x
Where F is the force, k is the force constant (also known as the spring constant), and x is the displacement.
Given that the force varies from 0 N to 63.5 N and the displacement is 5.31 cm (which we'll convert to meters), we can substitute these values into the equation and solve for k.
Using the formula F = k * x:
63.5 N = k * 0.0531 m
Dividing both sides of the equation by 0.0531 m gives:
k = 63.5 N / 0.0531 m
Calculating:
k ≈ 1196.03 N/m
Therefore, the force constant of the spring is approximately 1196.03 N/m.

To find the force constant of the spring, we can use Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position.
Hooke's Law can be expressed as:
F = k * x
Where:
F is the force applied to the spring
k is the force constant of the spring
x is the displacement of the spring from its equilibrium position
In this case, we are given that the force required to stretch the spring varies from 0 N to 63.5 N as we move one end 5.31 cm from its unstressed position.
Let's calculate the force constant (k) using the given information:
F = 63.5 N (maximum force required)
x = 5.31 cm (displacement)
We need to convert the displacement from cm to meters since the force constant should be in units of N/m:
x = 5.31 cm = 5.31 * 0.01 m = 0.0531 m
Now we can solve for k:
F = k * x
63.5 N = k * 0.0531 m
To find k, we can rearrange the equation:
k = F / x
k = 63.5 N / 0.0531 m
Evaluating the expression:
k ≈ 1197.5 N/m
Therefore, the force constant of the spring is approximately 1197.5 N/m.
