A pellet of mass ' $m$ ' and specific heat capacity 'c' fired from an air gun hits a steel plate with speed ' $v$ '. During the impact, $50 \%$ of the pellet's kinetic energy is converted to thermal energy in it. The rise in the temperature of the pellet is
  1. $\frac{v^2}{2 c}$
  2. $\frac{v^2}{4 c}$
  3. $\frac{m v^2}{2 c}$
  4. $\frac{m v^2}{4 c}$
