Question

If a 6N weight is hung on a spring, and it extends by 0.2m, what is the spring constant (k)? What do you think the units are?

Answer 1

K = 30N/m

Step-by-step explanation:

We use this equation:

F= k∆x

Where ∆x refers to the amount or stretch or compression and k is the spring constant.

F = force

k = spring constant

∆x = change in length of spring

We don't know the value of k, so we make k the subject:

k = F/∆x

k = 6N x 0.2m

k = 30N/m
