```Except for some constants the essential behaviour of Maxweell-Boltzmann
distribution is determined by
v**2 * exp(-v**2)
The following code will gove you
a plot of the shape of the curve.

from matplotlib import pyplot as plt
import numpy as np
f = np.zeros(40)
v = np.arange(0,4,0.1)
for i in np.arange(0, 40):
f[i] = v[i]**2*(np.exp(-v[i]**2))
plt.plot(v,f)
plt.show()

regards,
Sarma.
