    A spring constant stores 25J of energy when compressed by 7.5cm
    a) Find the spring constant
    b) Find the force to compress the distance

    For part (a), you'll need to know the equations to find the spring constant based off of the energy [E] that is exerted to move it the distance [x] it moves, which is also equal to its amplitude [A].

    For (b), the force exerted can be found by using the spring constant value you found in (a) and muliplying it by the distance it is compressed.
