Example 1 a. What is the final velocity of the boy?

Example 1 b. How far apart are they after 5.0 s?

Example 2 a. What is the final velocity of the bullet and the block after the collision?

This is known as a completely inelastic collision. Example 2 b. What are the initial and final kinetic energies of the bullet, wood block system? This is known as a completely inelastic collision.
