There are several objects that can travel faster than the speed of sound, also known as supersonic speed. Here are a few examples:
Supersonic Aircraft: Certain military jets, such as the Lockheed SR-71 Blackbird, the Mikoyan MiG-31, and the North American X-15, are designed to fly at supersonic speeds. These aircraft can achieve speeds well beyond the speed of sound.
Supersonic Bullets: Specialized bullets fired from firearms, such as the .220 Swift and .204 Ruger cartridges, can travel faster than the speed of sound. These bullets are designed for long-range shooting and can reach velocities exceeding Mach 3 (three times the speed of sound).
Supersonic Projectiles: Some artillery shells and projectiles used in military applications, like the Hypervelocity Projectile (HVP), can attain speeds greater than the speed of sound. These projectiles are designed for increased accuracy and range.
Supersonic Trains: Maglev trains, which utilize magnetic levitation to eliminate friction, have the potential to reach supersonic speeds. However, currently operational maglev trains, such as the Shanghai Maglev Train, have not exceeded the speed of sound.
Supersonic Vehicles: Experimental land vehicles, such as the Thrust SSC (SuperSonic Car) and the Bloodhound SSC, are built to break the land speed record and achieve supersonic speeds. The Thrust SSC became the first car to break the sound barrier in 1997.
It's worth noting that objects traveling faster than the speed of sound create a sonic boom, which is a loud noise caused by the shock waves generated by the object as it moves through the air.
