Answer:
75.544 N.
Explanation:
From Hooke's law,
Applying,
F = ke.............................. Equation 1
Where F = Force required to stretch the spring, k = force constant of the spring, e = extension.
From the question,
Given: k = 266 N/m, e = 28.4 cm = 0.284 m
Substitute these values into equation 1
F = 266(0.284)
F = 75.544 N.
Hence the force required to stretch the spring is 75.544 N
