$3,$ Calculate the Ar speed distribution at different temperatures

$(1)$ Simulate the velocity and speed of a total of $8000Ar$ atoms by running the job file $"$Ar$\_$speed.xm$"($uploaded on Canvas$).$

$(2)$ Write a script named "speed$\_$distribution" to: $(2-$a$)$ Import the velocity components $(v_x,v_y,v_z)$ for each of the $8000$ atoms contained in the V$\_200$K$.$dat file, and calculate the speed $)$ for each atom. $(2-$b$)$ Find the maximum and minimum values of speed $($s$),$ and choose $20$ intervals $($with interval width defined as $\{$:$\frac{s_{\text{m}\text{a}\text{x}}-S_{\text{m}\text{i}\text{n}}}{20})$ that spans from $S_{\text{m}\text{i}\text{n}}$ to $S_{\text{m}\text{a}\text{x}}.(2-$c$)$ Count and number of and the probability $(P_s)$ of speed that lies in each of the $20$ intervals. $(2-$d$)$ Plot the curve of probability $(P_s)$ vs$.$ speed range. $(3)$ Repeat $(1)(4)$ for $400K,600K,800K$ and $1000K,$ compare the results.
