# Does a towel whip break the sound barrier?

We have used high-speed photographic methods to show that the tip of the towel does indeed break the sound barrier. An experiment reported by Bern- stein et al. ' in 1958 showed that the tip of a cracked bull whip exceeds the speed of sound.

## Do whips break sound barriers?

The tip of a bullwhip is thought to be the first human-made object to break the sound barrier, resulting in the telltale "crack" of the whip. This "crack" sound is actually a small sonic boom. To break the sound barrier, you (or your bullwhip) must exceed about 770 mph at sea level.

## What things can break the sound barrier?

An airplane, a bullet, or the tip of a bullwhip can create this effect; they all produce a crack. This pressure change created by the sonic boom can be quite damaging. In the case of airplanes, shock waves have been known to break windows in buildings.

## How loud is a whip crack?

The loudest whip crack is 148.7 db(A), and was achieved by Adam Winrich (USA), at the Eau Claire Children's Theatre in Eau Claire, Wisconsin, USA, on 21 June 2017.

## Can a sling break the sound barrier?

It would be really hard for a projectile from a sling to go faster than the speed of sound. I remember from an earlier thread that for a rock to be thrown 500 yards (about 450 m), it'd would be traveling at about 200 km/h. The speed of sound is roughly 1100 km/h.

## Can the pistol shrimp break the sound barrier?

Pistol shrimps - which stun their prey by snapping their claws together to create a deafening 'crack' Despite being less than an inch long, the creatures can emit an astonishing 218 decibels. The sound stuns small fish and crabs, allowing the shrimp to move in for the kill.

## Why does a whip hurt?

The reason, a Whip hurts so much is that the tip of whip moves extremely fast, causing the skin to tear. The reasoning behind this is easy to analyze from momentum conservation. Lets take a convenient approximation, that the mass per unit length(ρ) does not vary through the length of the whip.

## Do pilots hear sonic boom?

If you're WONDERing about how pilots handle sonic booms, they actually don't hear them. They can see the pressure waves around the plane, but people on board the airplane can't hear the sonic boom. Like the wake of a ship, the boom carpet unrolls behind the airplane.

## Why do we no longer hear sonic booms?

In the 1950s and '60s, Americans filed some 40,000 claims against the Air Force, whose supersonic jets were making a ruckus over land. Then in 1973, the FAA banned overland supersonic commercial flights because of sonic booms—a prohibition that remains in effect today.

## Is it legal to break the sound barrier?

It's against the law. Within the United States, it is illegal to break the sound barrier. The Federal Aviation Administration regulations are quite clear: "No person may operate a civil aircraft in the United States at a true flight Mach number greater than 1" except in certain, very limited conditions.

## Can a whip go supersonic?

"The crack of a whip comes from a loop traveling along the whip, gaining speed until it reaches the speed of sound and creates a sonic boom," Goriely says. He notes that even though some parts of the whip travel at greater speeds, "it is the loop itself that generates the sonic boom."

## Can a bird break the sound barrier?

The bird stands bolt upright on a log, leans back on his tail, and fans his wings vigorously – so fast, in fact, that the wings achieve the same speed as the sound waves generated by their passage through the air. This causes the sound waves to “pile up” into a penetrating shock wave, also known as a sonic boom.

## Was the whip the first thing to break the sound barrier?

A: The Whip! The cracking sound a bullwhip makes when properly wielded is, in fact, a small sonic boom. The end of the whip, known as the “cracker”, moves faster than the speed of sound, thus creating a sonic boom. The whip is probably the first human invention to break the sound barrier.

## Do race horses feel the whip?

Two papes published in journal Animals lend support to a ban on whipping in horse racing. They respectively show that horses feel as much pain as humans would when whipped, and that the whip does not enhance race safety.

## Is whipping a horse animal cruelty?

Whipping the horses over and over again inflicts physical and psychological pain and increases the likelihood of injury. Somehow, the racing industry has escaped accountability for this blatant act of animal cruelty.

## Are jockeys allowed to whip horses?

During the last 100m of a race, whips can be used at a jockey's discretion, which essentially means horses can be whipped most when they are at their most fatigued and least able to respond.

## What animal punches hardest?

Mantis shrimp pack the strongest punch of any creature in the animal kingdom. Their club-like appendages accelerate faster than a bullet out of a gun and just one strike can knock the arm off a crab or break through a snail shell. These small but mighty crustaceans have been known to take on octopus and win.

## What creature has the fastest punch?

The Mantis Shrimp Has the World's Fastest Punch.

## Which animal has the fastest strike?

Watch: Dracula ant's killer bite makes it the fastest animal on Earth. The Dracula ant can strike 5,000 times faster than the blink of an eye, beating the old equivalent speed record by a factor of three. The jaw of a Dracula ant goes from 0 to 200 miles per hour in 0.000015 seconds.

## Can an arrow break the sound barrier?

Canada's first Arrow, RL 201 flew for the first time on March 25, 1958. Built at a time when aircraft typically could only break the sound barrier speed of Mach 1.0 in a dive - the Arrow RL 201 broke the sound barrier in a steep climb on only it's third flight on April 3, 1958.

## How fast was David's slingshot?

The sling could hurl a stone of 25 grams (about 1 oz.) at 100 kilometers per hour (62 mph) to hit something 200 meters (656 ft.) or more away.

## What was David's slingshot made of?
