    Spring compression -- Ball colliding with a spring-mounted platform

    I've tried establishing a systems of equations with -(1/2)kx^2+mpgx+(1/2)mpvp^2=0, but this leads to an annoying quadratic that when solved does not give one of the listed answers. My thought was that the spring's potential energy is going to be equal to the gravitational potential energy and...

    How can I calculate the potential energy stored in a compressed spring?

    I guess I overcomplicated that in my head. Thank you!

    How can I calculate the potential energy stored in a compressed spring?

    So would it just be the force applied * the displacement?

    How can I calculate the potential energy stored in a compressed spring?

    I feel like I've gotten stuck on this. I know the work done is equal to the kinetic energy of block A, but I can't figure out how I would find the potential energy stored in the spring without using the spring constant in the equation. W = FA * dA + U
