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
[tex]s=ut+\frac{1}{2}at^2[/tex]
here,
s is the distance
a is the acceleration
t is the time
on substituting the values, we get
[tex]370=0\times t+\frac{1}{2}\times9.81\times t^2[/tex]
or
t² = 75.433
or
t = 8.68 seconds
