Answer:
a) t = 4.14 s
b) Speed with which it hits the ground = 40.58 m/s
Explanation:
Using the equations of motion,
g = 9.8 m/s², y = H = 84 m,
Initial velocity, u = 0 m/s,
final velocity, v = ?
Total Time of fall, t = ?
a) y = ut + gt²/2
84 = 0 + 9.8t²/2
4.9t² = 84
t² = 84/4.9
t = 4.14 s
b) v = u + gt
v = 0 + (9.8 × 4.14)
v = 40.58 m/s
Answer:
The code is written in python in the explanation section below
Explanation:
a_feet = int(input("Input the feet of the first fabric: "))
a_inches = int(input("input the size in inches for the first piece of fabric: "))
b_feet = int(input("input the size in Feet for the second piece of fabric: "))
b_inches = int(input("Enter the size in Inches for the second piece of fabric: "))
sum_inches = a_inches + b_inches
inches_to_feet = sum_inches // 12
rem_from_div = sum_inches % 12
sum_feet = a_feet + b_feet + inches_to_feet
print("Feet: {} Inches: {}".format(sum_feet, rem_from_div))
