Question
If a force of 256 N is applied to a spring, the spring is stretched a distance of 9.50 cm from its equilibriumposition. What is the elastic constant of this spring?a. 2.69 x 103N/m c. 26:9`N/mb. 2.43 x 103N/m d. 243. N/m
Solution
The elastic constant of a spring, also known as the spring constant, is calculated using Hooke's Law, which states that the force needed to extend or compress a spring by some distance is proportional to that distance. The formula is:
F = kx
where: F is the force applied, k is the spring constant, x is the distance the spring is stretched or compressed.
Rearranging the formula to solve for k gives:
k = F/x
Given in the problem, F = 256 N and x = 9.50 cm = 0.095 m (since we need to convert cm to m because the standard unit of distance in physics is meters).
Substituting these values in:
k = 256 N / 0.095 m = 2694.7368421052633 N/m
Rounding this to three significant figures gives k = 2.69 x 10^3 N/m.
So, the elastic constant of the spring is 2.69 x 10^3 N/m. The answer is (a).
