"A penny is pretty much a little nothing," Bloomfield said. At that speed, it might very well damage your skull, but it wouldn't drill through. If there were no air, a falling penny would accelerate to a speed of 208 mph (335 kph) by the time it reached the ground (or your head). After that point, they flutter to the ground at a measly 25 mph (40 kph), Bloomfield said. Thus, if hurled off a skyscraper, pennies achieve their terminal velocity after only about 50 feet (15 meters) of descent. Pennies are flat, so they experience a lot of air resistance, and they are light, so it doesn't take much drag to counteract their weight. Instead it falls at a constant speed, called the terminal velocity, all the way to the ground. With the two forces balanced, the penny no longer accelerates. The faster the penny falls, the greater the air resistance it experiences, and so at a certain maximum velocity of the penny, the drag force becomes equal and opposite to the downward gravitational force. Called a "drag force," air resistance opposes the penny's downward motion, counteracting the force of gravity. This would indeed happen if New York City was evacuated - that is, if all the air were removed and the penny was tossed off the Empire State Building into a vacuum - but as things are, collisions with air molecules slow falling pennies down. People mistakenly assume that a falling penny, subject to the force of gravity, will accelerate for the entirety of its fall, achieving breakneck speeds by the time it reaches the ground. "I think one bounced off my face once," Bloomfield told Life's Little Mysteries. When experimental pennies struck him, it didn't hurt. He recently used wind tunnels and helium balloons to replicate the fall of pennies from skyscrapers. If it did strike you, it would feel like being flicked in the forehead - "but not even very hard," said Louis Bloomfield, a physicist at the University of Virginia. Instead, it would flutter to the ground, like a leaf. Even from that height, a penny is too small and flat, and cushioned by too much air, to become a torpedo. In fact, it's extremely difficult to turn a penny into a lethal weapon, and hurling it over the barricades at the top of the Empire State Building won't get the job done. ![]() You can rest easy - on that score, at least. However, Kinga Ka is still faster, with speeds up to 128 miles per hour.City-slickers: Have you ever worried that, at any moment, you could be struck dead by a penny flung off the roof of a nearby skyscraper? Skyscraper replaces Kinga Ka at Six Flags Great Adventure as the world's tallest roller coaster. That, in and of itself, is quite a ride, and will take visitors 535 feet above the ground, where they can visit the structure's observation deck. The tower itself will be the tallest building in central Florida, with the top accessible via a 55-story glass elevator ride. ![]() "It is an absolute cutting-edge engineering marvel that will deliver pure adrenaline unlike any roller coaster in the world today." "Skyscraper will not only take riders higher than ever before, but also introduce one thrill right after the next- there's no 'down time' on this four-minute coaster experience," says Michael Kitchen, president of US Thrill Rides. If that hasn't horrified you or made you lose your lunch, you can ride Skyscraper yourself in 2017. For authenticity, the video also includes realistic screams of terror. Eventually, the cars curl around the rest of the entertainment complex. But what goes up, must also go down, and the cars drop and hit speeds up to around 65 miles per hour as they race around the tower, throwing the rider into sudden drops and corkscrews. The simulated ride shows a full four-minute Skyscraper ride with the coaster's cars climbing up a track that surrounds a tower. Thrill Rides, released a video of a virtual ride. To get an idea of what Skyscraper is like, the coaster's builder, U.S. ![]()
