A bullet with a mass of 45 g is fired upward through a hole in a table into a block of wood with a mass of 5.2 kg. The bullet lodges in the block and the two rise to a height of 3.1 m above the table.

1. Calculate the potential energy of the block above the table.

2. Calculate kinetic energy and velocity of the block as it left the table.

3. Calculate the velocity of the bullet as it struck the block.

4. Calculate the kinetic energy of the bullet immediately before it struck the block.
