Objects that can travel faster than the speed of sound are generally designed for high-speed transportation or military purposes. Here are some examples:
Supersonic Aircraft: Certain military aircraft, such as the Lockheed SR-71 Blackbird and the Mikoyan MiG-31, are capable of traveling at speeds exceeding the speed of sound (Mach 1). The retired Concorde passenger airliner was also capable of supersonic speeds.
Supersonic Missiles: Various missiles, including anti-ship missiles and air-to-air missiles, can travel faster than the speed of sound. These missiles are designed to strike targets quickly and with high precision.
Bullets: Some specialized bullets fired from firearms can exceed the speed of sound. These projectiles are known as supersonic ammunition.
Projectiles and Artillery Shells: Certain artillery shells, tank rounds, and projectiles fired from large-caliber guns can also reach supersonic velocities.
Spacecraft: Vehicles designed for space exploration, such as crewed spacecraft and satellites, can travel far beyond the speed of sound. For example, during reentry into the Earth's atmosphere, space capsules experience speeds greater than the speed of sound.
It's important to note that the speed of sound varies depending on factors like altitude, temperature, and humidity. At sea level and at a temperature of around 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound is approximately 343 meters per second (1,125 feet per second) or 1,235 kilometers per hour (767 miles per hour).
