Kinetic energy of the pile driver is 10 KJ.

To find the answer, we need to know about the conservation of mechanical energy.

What's the conservation of mechanical energy?

Conservation of mechanical energy says that the total energy of a system remains same during a process.

What's mechanical energy?

  • Mechanical energy is the sum of potential energy and kinetic energy.
  • As the mechanical energy is conserved, so when the potential energy is decreased the kinetic energy is increased with same amount that of decreased potential energy.

Thus, we can conclude that the increased kinetic energy is 10KJ.
