A 0.940 kg block is attached to a horizontal spring with spring constant 2550 N/m. The block is at rest on a frictionless surface. A 7.90 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 10.2 cm?
