Answer: 95N
Step-by-step explanation:
Force necessary to stretch a spring = ?Extension of spring, e = 0.5 m
Spring constant, k = 190 N/m
Apply the formula for Hooke's law,
Force = Spring constant x extension
i.e F = ke
F = 190 N/m x 0.5 m
F = 95 N
Thus, 95 Newton of force is necessary to stretch the spring
