A 1.00 kg block is attached to a horizontal spring with spring constant 2500 N/m. The block is at rest on a frictionless surface. A 20 g bullet is fired into the block, in the face opposite to the spring and sticks.

What is the bullet's speed if the subsequent oscillations have an amplitude of 10.0 cm?
