write a python program

Question

Consider the following formula and evaluate the y value for the range of t values found in a file with format 𝑦(𝑡) = 𝑣0𝑡 − 0.5𝑔𝑡

File Format:

v0 3.0

t:

0.15592 0.28075 0.36807889 0.35 0.57681501876 0.21342619 0.0519085 0.042 0.27 0.50620017 0.528 0.2094294 0.1117 0.53012 0.3729850 0.39325246 0.21385894 0.3464815 0.57982969 0.10262264 0.29584013 0.17383923

i. Write a function that reads the input file and returns v0 and a list with the t values.

ii. Write a function that creates a file with two nicely formatted columns containing the t values to the left and the corresponding y values to the right. Let the t values appear in increasing order (note that the input file does not necessarily have the t values sorted).

iii. Make a test function that generates an input file, calls the function for reading the file, and checks that the returned data objects are correct.

iv. Write a function which handle the exception handling for the availability of file or not.

tValues = [0.15592, 0.28075, 0.36807889, 0.35, 0.57681501876, 0.21342619, 0.0519085, 0.042, 0.27, 0.50620017, 0.528, 0.2094294, 0.1117, 0.53012, 0.3729850, 0.39325246, 0.21385894, 0.3464815, 0.57982969, 0.10262264, 0.29584013, 0.17383923]

tValues.sort()

v0 = 3.0

g = 9.8

N = len(tValues)

print(" t y ")

for i in range(N):

t = tValues[i]

y = float(v0)*float(t) + float(g)*float(t)/2

print(str(t) + " " + str(y))
