A 1.2kg block is dropped from 48cm above a spring in equilibrium. The force constant for the spring is 124N/m. Calculate the maximum compression in the spring.

If X is maximum spring compression, and H is the height from which the block falls (0.48 m), conservation of energy tell you that

M g (H + X) = (1/2) k X^2

where k is the spring's force constant.

Solve for X

Take the positive root of the resulting quadratic equation.
