Hello world!
This is the current date and time, as computed by Python: import matplotlib.pyplot as plt import numpy as np import matplotlib.animation as animation t = np.linspace(0, 3, 20) g = -9.81 v0 = 12 z = g * t**2 / 2 + v0 * t v02 = 5 z2 = g * t**2 / 2 + v02 * t print( "Vitesse = " + v02) print( "r2 = " + v02)
