Answer:
0.281 m
Explanation:
Applying,
W = 0.5ke².................. Equation 1
Where W = Workdone by the stretched spring, k = spring constant, e = extension/ compression of the spring
make e the subject of the equation
e = √(2W/k)................ Equation 2
From the question,
Given: W = 1.240J, k = 31.50 N/m
Substitute these values into equation 2
e = √(2×1.240/31.50)
e = √(0.07873)
e = 0.281 m
