# A bullet at speed v_0 hits and embeds into a wood block hanging from a string, which rises height h. Which is true about the collision?

A bullet at speed \( v_0 \) trikes and embeds itself in a block of wood which is suspended by a string, causing the bullet and block to rise to a maximum height h. Which of the following statements is true?

- **A.** The initial kinetic energy of the bullet before the collision is equal to the kinetic energy of the bullet and block immediately after the collision.
- **B.** The initial kinetic energy of the bullet before the collision is equal to the potential energy of the bullet and block when they reach the maximum height h.
- **C.** The initial momentum of the bullet before the collision is equal to the momentum of the bullet and block at the instant they reach the maximum height h.
- **D.** The initial momentum of the bullet before the collision is equal to the momentum of the bullet immediately after the collision.
- **E.** The kinetic energy of the bullet and block immediately after the collision is equal to the potential energy of the bullet and block at the instant they reach the maximum height h.
