A 0.300 kg block of wood rests on a horizontal frictionless surface and is attached to a spring (also horizontal) with a 28.0 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 in centimeters by which the Play-Doh-block system compresses the spring.
