A bullet of mass m is moving horizontally with speed vo when it hits a block of mass 100m that is at rest on a horizontal frictionless table, as shown above. The surface of the table is a height h above the floor. After the impact, the bullet and the block slide off the table and hit the floor a distance x from the edge of the table.

a) Make a bar graph including momentum. Tell whether it is conserved or constant. b) What is the final velocity? c) What is the change in kinetic energy? Is it elastic or inelastic?
