1.20kg mass is dropped from a height of 0.9M unto a spring with force constant K= 120N/m and negligible mass. Find the maximum distance the spring will compressed

pls show full working and indicate formular.

    At maximum compression X, the spring's potential energy will equal the gravitational potential energy loss.

    M g (H +X) = (k/2)*X^2

    Solve for X
