I am having trouble generating a plot. in this program, the program takes a final time (tF) value and the initial time (tI) value and subtracts them to get a (delta T) that delta T is then plugged into the terminal velocity equation (vT). The goal is to take the delta T and vT and place them into a plot. (Terminal velocity cannot exceed 2). the plot is generated however, there is no data point on that plot. Please help!!

import numpy as np import matplotlib.pyplot as plt

def problem4C():

tF = 0.008 vI = 0 g = 10 m = 10 c = 50 tI = 0 vMax = 2 i=0

#Loops for certain number of delta T's

while True: for i in range(14):

#delta T

t = tF-tI

#Terminal velocity equation

vT = vI+(g -((c/m)*vI))*(t)

#Replaces V inital with terminal velocity answer vI = vT

i = i+1 #print(vT)

#reaches 14 interations

if i == 14:

if vT > vMax: tF = tF-0.0001 continue elif vT

#Error eT = ((vMax - vT) / vMax)*100

#round error to 2 decimal places

eT = round(eT,2)

#checks to see if velocity is 99.99 percent correct if eT != 0.01:

tF = tF + 0.001

continue

elif eT == 0.01:

print("Time required to reach 99.99 percent terminal velocity:",round(tF,4), "s")

#plot t = np.array() plt.plot(t,vT) plt.show()

break
