Question

I'm trying to model the velocity over time of a given time interval in python, but my code won't work. I need to solve the problem using the Euler method.

import numpy as np
from matplotlib import pyplot as plt


def car(x0, v0, Cd, p, A, m, facc, T, dt):
    n = 0
    t = np.arange(0, T, dt)
    x = np.array([x0])
    v = np.array([v0])

    while x[n] > 0:
        x = np.append(x, x[n]+v[n]*dt)
        v = np.append(v, v[n]+(facc/m-(1/(2*m))*Cd*A*p*v[n])*dt)
        t = np.append(t, t[n]+dt)
        n += 0
    return x, v, t

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

Note: Brother sometimes while uploading on HomeworkLib the indentations change. So, I request you to verify it with screenshot once. This is the link where I have saved the code too

import numpy as np
def car(x0, v0, Cd, p, A, m, facc, T, dt):
n = 0
t = np.arange(0, T, dt)
x = np.array([x0])
v = np.array([v0])

while x[n] > 0:
x = np.append(x, x[n]-v[n]*dt)
v = np.append(v, v[n]+(facc/m-(1/(2*m))*Cd*A*p*v[n])*dt)
t = np.append(t, t[n]+dt)
n += 1
return x, v, t
car(1,12,0.8,5,10,5,76,7,0.01)

Kindly revert for any queries

Thanks.
