33627.4 N/m

Explanation:

By Hook's law F = k x

where F = force applied

K = Spring constant

x = distance it compresses.

Since the force applied in this case will be the weight of the object that causes it to compress, so, the weight will be (175 * 9.8) = 1715N force which causes a compression (x) of 0.0510m.

So,

F = K x

K = F / x

K = 1715 / 0.0510

K = 33627N/m
