A 0.940 kg block is attached to a horizontal spring with spring constant 1600 N/m . The block is at rest on a frictionless surface. A 8.00 g bullet is fired into the block, in the face opposite the spring, and sticks. The subsequent oscillations have an amplitude of 13.0 cm .

A) Find the total energy of the oscillator.

B) Find the speed of the bullet and block immediately after the collision.

C) Find the speed of the bullet just before it hits the block.
