C$.$ Sketch the main game loop to model the uniform motion of a particle starting from $(0,0,0)$

in the direction specified by vector $(1,2,3)$ with a constant speed of $5$ units per second.

You answer should take the frame rate into account.

Let pos :$=(0,0,0)$

Let U:$=(1,2,3).$ normalize $()$

While $($loop not finished$)$

$-$pos:$=$pos$+5**$tpf$**$U

D:A ball with coordinates $(5,2,0)$ moves uniformly with a constant speed given by vector $(2,0,0).($a$)$ Sketch the main game loop to model the uniform motion of the ball. You answer should take the frame rate into account. $5$ marks PAPER CODE COMP$222$ page $8$ of Let pos :$=(5,2,0)$ Let V :$=(2,0,0)$ While $($loop not finished$)$ pos :$=$ pos $+5$ tpf $$ V

I have a question what is the difference between the two c$,$d and why the answer in questionc normalize and the answer in d the v did not normalize, and what the meaning of $5,$ is it the speed? But if $5$ is the speed, the speed in d is $2$ who can help me
