Question

Please answer using Python Pycharm programming.

y(t)vot gt for vo 10,9 9.81 3. Make a plot of the function and [O, 2vo/gl. Set the axes labels as time (s) and height (m). 4. Create an array W with values 0, 0.1, 0.2, ...., 3. Write out WI:], WI:-2], W[:5], W[2:-2:6] Convince yourself in each case that you understand which elements of the array that are printed.

Answer 1

Code:

3.

import numpy as np
import matplotlib.pyplot as plt

vo = 10
g = 9.81

t = np.arange(0, 2*vo/g,0.1)

y = vo*t- (g*t*t)/2
plt.plot(t,y)
plt.xlabel('time(s)')
plt.ylabel('height(m)')

Output:

4.

import numpy as np

W = np.arange(0, 3.1,0.1)
print(W[:]) #print all elements of W
print(W[:-2]) # prints all elements except last 2
print(W[::5]) #print all elements at step size of 5
print(W[2:-2:6]) #prints from index 2 till length(W) - 2 with a step of 6

Output:

[0. 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.91. 1.1 1.21.3 1.4 1.51.6 1.7 1.8 1.9 2. 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 3. ] [0. 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.91. 1.1 1.21.3 1.4 1.51.6 1.7 1.8 1.9 2. 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8] [0. 0.51. 1.5 2. 2.53. ] [0.2 0.81.4 2. 2.6]
