    Having a brain block on this question- just not sure where to start so any help would be appreciated!

    Two light elastic strings each have natural length 0.75m and modulus of elasticity 49N. A particle P or mass 2kg is attached to one end of each string. The other ends of the strings are attached to fixed points A and B, where is AB is horizontal and AB is 1.5m.

    The particle is held at the mid-point of AB. The particle is released from rest:

    a) Find the speed of P when it has fallen a distance of 1m.


    Thanks in advance!

    Do you know the equation, elastic potential = (Lamda)x^2/2l ?

    If so it's just an energy equation.

    Edit: looking at it its a bit more difficult, I can give you more of a clue if you still don't get it.

    Nope I've got it now, just needed a push in the right direction to stop me staring blankly at the page!

    Thanks very much.

    No problem

    Elasticity is my favourite topic on M3, as long as it's not circular motion or SHM I'm happy to help.
