How much work is required to stretch a spring 25.2 cm if its force constant is 12.3 N/m?
A) 0.391 J
B) 0.488 J
C) 3.10 J
D) 1.05 J
E) 0.381 J

Quizplus · Accepted Answer

The work done in stretching the spring can be calculated using the formula: W = (1/2)kx^2, where k is the force constant of the spring and x is the displacement from its equilibrium position.
Given: k = 12.3 N/m and x = 25.2 cm = 0.252 m
Therefore, W = (1/2) * 12.3 * 0.252^2 = 0.391 J, which is the closest option to the calculated value. Hence, the correct answer is (A).
