A horizontal spring with k = 71N/m has one end attached to a wall and the other end free. An 84g wad of putty is thrown horizontally at 3.8m/s directly toward the free end.

Find the maximum spring compression (ignore gravity). Note: Kinetic energy is converted into potential energy of spring.

Thanks!

Figured it out, in case anyone wants to know here it is.
$$x = \sqrt{\frac{  mv^{2} }{ k }}$$
x =displacement
m = mass
v = velocity
k = kinetic energy
