How much force is necessary to stretch a spring 0.5 m when the spring constant is 190 N/m

95N

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
