Eiffel Tower

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.

The Eiffel Tower is an iron lattice tower located in Paris, France, and is one of the most well known landmarks in the world.

The tower was completed in 1889. It serves as a tourist attraction, a venue for observations of the city of Paris, and as a location for TV and radio broadcast antennae. Named for its designer, engineer Gustave Eiffel, the tower was built as the entrance arch to the 1889 World's Fair.

The tower stands 324 metres (1,063 ft) tall, about the same height as an 81-storey building. It was the tallest man-made structure in the world from its completion until the Chrysler Building in New York City was built in 1930. Not including broadcast antennas, it is the second-tallest structure in France after the 2004 Millau Viaduct.

The tower has three levels for visitors. Tickets can be purchased to ascend, by stairs or lift, to the first and second levels. The walk to the first level is over 300 steps, as is the walk from the first to the second level. The third and highest level is accessible only by lift. Both the first and second levels feature restaurants.

The tower has become the most prominent symbol of both Paris and France, often in the establishing shot of films set in the city.
The Eiffel Tower is a famous monument. It is an iron lattice tower on the Champ De Mars.
The Eiffel Tower (French: Tour Eiffel, [tuʀ ɛfɛl]) is a 19th century iron lattice tower located on the Champ de Mars in Paris that has become both a global icon of France and one of the most recognizable structures in the world. The Eiffel Tower, which is the tallest building in Paris,[10] is the single most visited paid monument in the world; millions of people ascend it every year.
Work on your grammer >:(

The eiffel tower is a block of very tall metal. I love the view from there though :)
