# Write a function that calculates how long an object will take to
# fall to the ground from a certain height.
# The formula to calculate the time taken for an object to fall is:
# time = sqrt(2 * height / g)
# where:
#       time - time taken for the object to fall
#       height - height from which the object is dropped
#       g - acceleration due to gravity (9.81 m/s^2)

# import math

# g = 9.81

#       height - height from which the object is dropped
