A thin uniform circular disc rolls with a constant velocity without slipping on a horizontal surface. Its total kinetic energy is

• Correct answer
  A

  $\text { three times its rotational kinetic energy }$
• B

  $\text { three times its translational kinetic energy }$
• C

  $\text { one and half times its rotational kinetic energy }$
• D

  $\text { twice its translational kinetic energy }$

Hence, the correct answer is option: 'A'.
