Question

1. The final velocity v of an object is given by the formula v=u+a∙t , where u is the initial velocity, a is the acceleration and t is the elapsed time. (use python language to write a program with comments to perform the required tasks)
   1. Calculate and print the final velocity of an object with initial velocity of 15 m/s and acceleration of 2.5 m/s² after t = 18 seconds.   
   2. If an object starts from rest, how long will it take to reach a final velocity of 100 m/s, if the acceleration is 2.5 m/s². Display the result rounded to the nearest second.

Answer 1

CODE

def getFinalVelocity(u, a, t):

return u + a * t

def getTime(u, v, a):

return round((v - u) / a)

v = getFinalVelocity(15, 2.5, 18)

t = getTime(0, 100, 2.5)

print("Final velocity = %f m/s" %v)

print("Time taken = %d seconds" %t)
