A bullet with a mass b=11.9g is fired into a block of wood at velocity b=265m/s. The block is attached to a spring that has a spring constant of 205N/m.. The block and bullet continue to move, compressing the spring by 35.0cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass w of the woodenblock.

A bullet with a mass my = 11.9 g is fired into a block of k wood at velocity up = 265 m/s. The block is attached to a Vb spring that has a spring constant k of 205 N/m. The block m MM WW 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 mw of the wooden block. my = kg
