Who knew it would take following a humanities scholar in another country to get me interested in doing physics again?

OK, this is an energy balance problem! The gravitational potential energy is assumed to be fully converted into the spring energy. Which gives you the extension.

This makes sense to her tho not to me.

Nope. She still doesn't know what to do with this. Arghhhhhhhhh!!!!!!

The spring is dropped and the higher you drop it from the more it compresses. Makes sense, non? So, what's going on is that the gravitational potential energy is being converted into the spring energy. Need formulae for both. Then set equal.

What is g?

g = 9.8 m / s^2. The force acting on a particle is F = m g, where m is the mass. The gravitational potential energy of a particle at height h is given by U = m g h.

TBH, it's not a trivial question, cos it requires a fairly deep understanding of the concept of potential energy, which she may not yet have.

She is going to find her teacher at lunchtime coz this is an example of the test she has to do after lunch.
