Do not try this, because it is dangerous to the people and property below.

The actual terminal velocity would be difficult to compute because there are multiple forces acting on a quarter as it falls: gravity, air resistance from it falling, and natural wind. The air resistance or drag depends on the density and viscosity of the air, which would vary with air pressure and humidity and temperature, to name a few variables. Also affecting air drag is the cross-section of the object falling, which for a coin will be changing as the coin tumbles through the air. I can tell you how to figure the gravity portion, though.

Two equations to describe an object falling in a vacuum (no wind, no air drag):

Vfinal = Vinitial + a*t and D = Vinitial * t + (a/2)*t2

V is velocity, t is time, a is acceleration, and D is distance. Taking Vinitial as zero, like you just dropped it and did not throw it, a = 9.8 m/s2, and D = 320 meters (see related link - there are observation decks at the 86th floor and 102nd floor. The website only mentioned an outdoor area at the 86th floor deck, which it said is 1050 feet (320 meters) high. Also it did not say the height of the 102nd floor, just that the entire building is 1454 feet tall, but I'm thinking this is the height of the entire building).

You don't know time, but can rearrange the two equations to get Vfinal = sqrt(2*a*D) = sqrt(2*(9.8 m/s2)*(320 m)) = 79.2 m/s, which works out to 177 miles per hour. (remember initial velocity assumed to be zero, and no wind or air resistance, though).

This is the maximum velocity an object could reach, but due to the other factors, it will be less than that. If for some way it was dropped from the 1454 feet (443.2 meters) then the maximum velocity at impact could be 93.2 m/s or 208.49 mph

### If you drop a penny from the top of the Empire State Building how far into the cement will it go?

The air resistance would slow it down so much that it probably wouldn't even leave a mark on the sidewalk. The popular myth that a penny dropped from the Empire State Building could kill someone is just that: a myth. See the Related Question below for more details.

### If you drop a pennie of the top of the Empire State Building can it go right through someones body?

yes because of gravity it causes the penny to reach maxemon velocity and crush any thing in its way.

### Egg drop idea?

The best way to do an egg drop s perhaps the simplest one. First take on egg,( I prefer free range eggs) then stand on a dinner chair and drop the egg. If you would like a bigger or different break try different surface like hardwood or concrete.

### Give an example of straight line motion including its cause and the effect?

example: if u put a small object on a roller coaster ride, it falls out in a straight line... example: if u go on the empire state building and drop a object in would drop to the ground in a straight line all the way down.

### If you drop a brick from the Empire State Building will it kill a person?

It depends on where the person is stricken. If the person is stricken anywhere on the head, it will most likely mean death. If the person is stricken anywhere but the head, then the person will survive, but will be badly damaged where the person was hit.

### If you drop a penny off the top of the Empire State Building will it go through the center of the earth?

No. The air resistance would slow it down so much that it probably wouldn't even leave a mark on the sidewalk. The popular myth that a penny dropped from the Empire State Building could kill someone is just that: a myth. See the Related Question below for more details.
