A.The observation deck of tall skyscraper 370 m above the street. Determine the time required for a penny to free fall from the
Ainat [17]

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

s=ut+\frac{1}{2}at^2

here,

s is the distance

a is the acceleration

t is the time

on substituting the values, we get

370=0\times t+\frac{1}{2}\times9.81\times t^2

or

t² = 75.433

or

t = 8.68 seconds
