A 10.0-g bullet is fired into, and embeds itself in, a 2.35-kg block attached to a spring with a force constant of 18.0 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? Note: You must use conservation of momentum in this problem because of the inelastic collision between the bullet and block.
