Hmm. We know that the mass of a spring is 0.25kg & the spring constant is 1 kN/m but we're being asked to factor in the extension and don't know what that means?

Force is proportional to the extension of the spring, but in the opposite direction to the extension.

Thank you! But how do we find out what the extension is from the mass and the constant?

Well, what's the problem? Mass hanging on a spring in equilibrium?

Oh I can't get a screenshot of it on her laptop! She's been asked to work out an equation that requires knowing the mass, the constant and the extension but has only been given the first two.

OK, Thanks. I'll show her. See if it makes sense.

You could also transpose this into a problem in probability theory, by just making up an answer and then calculating the odds of it being correct.

Clearly not hard enough.
