Answer:
8.68 seconds
Step-by-step explanation:
Given:
Height of the deck above the street, s = 370 m
Since the condition is of free falling
thus,
initial speed, u = 0
Acceleration of the penny = acceleration due to gravity, g = 9.81 m/s²
Now,
from Newton's equation of motion, we have

here,
s is the distance
a is the acceleration
t is the time
on substituting the values, we get

or
t² = 75.433
or
t = 8.68 seconds
the circumference is about 18.85
Answer:
285
Step-by-step explanation:
285÷3=95
285÷9=31.6666
