Formula for Kinetic energy (k) is ?

  1. k = (1/2).m.v.v.v

  2. k = 0.5m.v

  3. k = (1/2).m.v

  4. k = (1/2).m.v.v

D Correct answer
Explanation

The correct formula for kinetic energy is k = (1/2)mv², where m is mass and v is velocity. Option D correctly shows k = (1/2).m.v.v which represents mv². Option A has an extra v (v³), Option B is incomplete (0.5mv), and Option C only has mv (not squared).
