A 20.0 g bullet is fired аt 350 m/s impаcts а 3 kg blоck that is mоving tоwards the bullet at 2.0 m/s on a level frictionless surface. The bullet becomes completely embedded in the block. This combination then slides along the surface for 10 cm until it hits a massless spring with a spring constant of 300 N/m. How far is the spring compressed when the block-bullet combination comes to rest?
