For two objects A and B, if mass of A is same as mass of B and speed of A is twice as much as that of B, statement that is correct is

1. Kinetic energy of A = kinetic energy of B; because, kinetic energy is independent of speed of the object.
2. since kinetic energy is inversely proportional to speed of the object, the kinetic energy of A < kinetic energy of B
3. Kinetic energy of A = 1 ⁄ 4 × Kinetic energy of B
4. Kinetic energy of A = 4 × Kinetic energy of B
