Abullet with a mass mb=11.5 g is fired into a block of wood at velocity =265 m/s. the block is attached to a spring that has a spring constant 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 of the wooden block. from left to right, a bullet of mass m subscript b has a velocity of v subscript b with a velocity vector pointing directly to the right. the vector points toward a block that is attached on its right face to a spring of force constant k. the other end of the spring is attached to a fixed, vertical surface. mass of wooden block:
