A 0.330-kg block of wood rests on a horizontal frictionless surface and is attached to a spring (also horizontal) with a 29.5-N/m force constant that is at its equilibrium length. A 0.0600-kg wad of Play-Doh is thrown horizontally at the block with a speed of 3.00 m/s and sticks to it. Determine the amount by which the Play-Doh–block system compresses the spring?

i used conservation of energy and got 13.53 cm and its wrong.
