    This is the question (11) and my workings. I seem to have too many unknowns and I can't see what the original spring had to do with anything - different spring, a different modulus and a different mass.

    The Lambda/m = 200 seems to work out with the answers in the book. ( Lambda = 250g modulus = 50N) but can't get there from where I've got to.

    Pointer please.

    Haven't done the question, but I guess that they want you to find the particle mass m from the first spring scenario.

    Thanks. I've re-read the question and you are quite right - the mass is the same. Up until now I thought the mass had been changed too. All is explained, I hope.

    Thanks
