Answer: Difficult to calculate, but under 8.81 seconds.
Calculating how long it takes an object to fall a certain distance is a difficult question if you want an exact answer, but if you're willing to look at a simplified model (ignoring factors such as air resistance/frictions, which would be considerable), a crude approximation can be reached.

The acceleration due to gravity of an object is 9.81 m/s2 (meters per second per second) down. The amount of displacement resulting from a given acceleration over time is .5at2, where t is the amount of time (in seconds). The amount of displacement we need to equal is the height of the roof of the Empire State Building, 381 m (1250 ft).

After substituting our values into the displacement/acceleration equation, giving us -381 = .5(-9.81)t2. We can find our amount of time by isolating t. Doing this give us our final result of 8.81 seconds. If we assume that non-gravity factors would not be accelerating your decent, we can treat this as an upper limit to the result in real life. if you try you cant go past the bars

How ever if you decide to use feet units you come up with 6.154 seconds. Acceleration due to gravity is approximately -32.174 feet per second2. The Empire State building is 1250 feet tall. So the height, Y, at time, t, 0 is 1250.
The acceleration equation of the scenario would at first Y"=-32.174t. When we integrate this to find the velocity equation we recieve: Y'=-16.087t2+C. The integrating constant, C, would represent a starting velocity. Since the person "fell" off the building the initial velocity is 0, so Y'=-16.087t2. In order to find the position equation we integrate once more, yielding: Y=-5.36233t3+C. The integrating constant, C, in this case represents initial position which we know is 1250. So the position equation is: Y=-5.36233t3+1250. To find out when he hits the ground we solve for when height, Y, equals 0. 0=-5.36233t3+1250. This yields a time value of 6.1544 seconds.
*Note: This answer also ignores air resistance.

# Can you hit the ground jumping off the Empire State building?

Of course you can hit the ground, but you will not survive. DONT DO IT

# How long would it take for an object to hit the ground from 1248 ft tall building?

In a vacuum, just under 9 seconds. In the real world, more than that, but it depends on the shape of the object and the prevailing winds and air currents.

# How long would it take to hit the ground if you jumped from the Eiffel Tower?

  If we ignore air resistance and so assume constant acceleration (a):   s = 1/2at2   ...where s is displacement and t denotes time. Since the Eiffel tower is 324m.

# Who jumped off the Empire State Building?

  yes someone has!   well i dont really know but i know that 1 woman commited sucide and she tried to jump off the top but then she got blew back in from the winds....

6 feet

8-9 seconds

# Would a penny and quarter hit the ground at the same time if they were thrown off the Empire State Building?

  Not really. True that gravity affects all objects equally, but unless we're in a complete vacuum, we have to take into consideration wind resistance in the form of the r

# What would happen if you dropped a penny off the Empire State Building and it made it to the ground?

The penny would hit the ground. In all likelihood, neither the cement sidewalk nor the penny would be significantly damaged. The air resistance would slow the penny down too m

# If you throw a penny off the empire states building how long will it take to hit the ground?

Acceleration from gravity is 9.8 m/s2 or 32.2 ft/s2. The Empire State Building is 381 meters/1,250 feet tall. So if we throw a penny off the Empire State Building, its speed

# How long would it take to die if you jumped off the Empire State Building?

    Not long enough...

# If a penny is dropped off the Empire State Building how fast is it travelling when it hits the ground?

Exact speed is impossible to calculate because of wind resistance which varies as the coin tumbles in the air.

# Could you survive jumping off the Empire state building?

u most likely would die  if u made it to the ground floor
In Physics

# If you dropped a ball off a building from 84 meters high how long would it take to hit the ground?

We know that S=ut+.5gt*t here s=84m g=9.8m/s*s u=0 hence time is 4.14secs.

# If a ball was dropped from the top of Empire State Building how long would it take it to hit the ground?

It would take 1.20 seconds. Empire State rules!

# Has anyone ever jumped off Empire State Building?

Yes, since it's completion in 1931 about 40 people have jumped to their deaths off the Empire State Building (most of those during the 1940s). One woman jumped in 1979 only to

# What if you dropped two rocks off the empire state building one a lot bigger than the other which one would hit the ground first?

According to Newton, they would touch the ground at the same time. Answer #2: The above answer would be exactly right if there were no air to provide drag. Unfortunately for

# How do you jump off the empire state building and survive?

By using a parachute.
