import math Function I: Complete the following function called "cal_secs_ball_falling1". A ball is dropped from a tower of height h (in meters) with initial velocity zero. Function "cal_secs_ball_falling1" takes the height of the tower as input and RETURNS the time (in seconds) the ball takes until it hits the ground (ignoring air resistance). Refer to hw3.docx for the kinematic formula. Requirement(s); 1) The return value is an integer that only keeps the integer part of the computed result. def cal secs_ball_falling1(h): pass #Replace pass with your code Function II: Modify the following function called "cal_secs_ball_falling2": A ball is AGAIN dropped from a tower of height h (in meters) with initial velocity zero. Function "cal_secs_ball_falling2" takes the height of the tower as input and CALCULATES AND PRINTS the time (in seconds) the ball takes until it hits the ground, ignoring air resistance. Requirement(s); 1) The displayed time is a floating-point number (i.e., no rounding needed). 2) Function "cal_secs_ball_falling2" is a VOID function. def cal_secs_ball_falling2 (h): te #t is the number of secs the ball takes until hitting the ground #Insert your code of calculating t below. #Keep the following print statement as the last statement of this function. print (f"It takes (t) seconds for the ball to hit the ground.\n") Function III: Complete the following function called "cal_altitude" that calculates and returns the needed altitude h (in kilometers) above the earth's surface that the satellite must have so that it orbits the planet once every t minutes. Refer to hw3.docx for the formula used to calculate the altitude. Hint: The parameter t is in minutes and T in the given formula is in seconds! def cal_altitude(t): pass #Replace pass with your code Function IV: Complete the following function called "darw_grid" that draws a grid like the one shown in "hw3.pdf", which is only composed of '+','','I' and (space). Hint: Consider using string addition (concatenation) and multiplication (repetition). def draw_grid(): pass #Replace pass with your code #Function Calls: #Do NOT modify the following code!!! print (f'It takes (cal_secs_ball_falling1(100)) seconds for the ball to hit the ground.\n') cal secs_ball_falling2(100) print(cal secs_ball falling2 (100), \n') print(cal_altitude (90), '\n') 130') print(cal_altitude (45), draw orid() output It takes 4 seconds for the ball to hit the ground. It takes 4.515236409857309 seconds for the ball to hit the ground. It takes 4.515236409857309 seconds for the ball to hit the ground. None 279.32162537285967 -2181.5598978108233
