A photon with a frequency of $4\mathrm{.}45{10}^{22}Hz$ is scattered at an angle of $18\mathrm{.}0$ after colliding with an electron. The photon's final momentum after the collision is

$5\mathrm{.}28{10}^{-21}kg*\frac{m}{s}$

$3\mathrm{.}28{10}^{-21}kg*\frac{m}{s}$

$1\mathrm{.}25{10}^{-13}kg*\frac{m}{s}$

$2\mathrm{.}95{10}^{-11}kg*\frac{m}{s}$
