Spring constant

Question

A spring have a constant of 340n/m . How much force is required to compress it 0.5 m?

Answer 1

This is a question asking about springs using Hooke's Law. Hooke's Law relates the spring constant with the displacement from equilibrium by the following relationship:

F_s = -kx

When the spring is compressed, x takes a negative value

F_s = -kx

<=> -(340N*m^-1)(-0.5m)

F_s = 170N
