Problem Nine. A bullet with mass m = 20.0 g bullet is fired into a block with mass M=7.00 kg which is attached to a spring. The bullet is moving with a speed of 350 m/s at the moment of collision. After the collision, the block (with bullet embedded) compresses the spring to a maximum displacement of 48.0 cm. After the spring is compressed, the system undergoes simple harmonic motion. Find the magnitude of the velocity when the block (with embedded bullet) is a third of the way through a full amplitude. Give an answer in cm/s.
