A bullet with a mass mb=11.9g is fired into a block of wood at velocity vb=257 m/s The block is attached to a spring that has a spring constant kk of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass mwmw of the wooden block.
