Gravitational potential energy and kinetic energy — practice question

A body moving at a speed of $10\,\text{m s}^{-1}$ possesses kinetic energy of $1500\,\text{J}$. If the body’s speed is raised to $40\,\text{m s}^{-1}$, what kinetic energy does it now have?

  • A$4500\,\text{J}$
  • B$6000\,\text{J}$
  • C$24\,000\,\text{J}$
  • D$1\,350\,000\,\text{J}$
