A 0.840 kg block is attached to a horizontal spring with spring constant 1900 N/m . The block is at rest on a frictionless surface. A 9.60 g bullet is fired into the block, in the face opposite the spring, and sticks.

What was the bullet's speed if the subsequent oscillations have an amplitude of 11.1 cm ?
