Spring Question

    Spring Question!!!!

    A 250g block is dropped onto a relaxed vertical spring that has a spring constant of 2.5N/cm. The block becomes attached to the spring compresses the spring 12 cm before momentarily stoppoing.
    While the spring is being compressed, what work is done on the block by
    (a)The gravitational forces on it?

    Can anyone tell me where to start?

    (b)what work is done on the block by the spring?

    is it this simple:

    Ws = -0.5k(x^2)

    Ws = -0.018 Joules

    ?

    shouldn't the work done by gravity equal the work done by the spring?

    What is the usual definition of work?

    energy transferred to or from an object via a force acting on the object. energy transferred from the object is negative..energy transferred to the object is positive.

    Ok..So is my answer Correct
