Yes, it is possible for certain objects or vehicles to travel at speeds equal to or greater than the speed of sound, which is approximately 343 meters per second (or 1,125 feet per second) in dry air at sea level and at a temperature of 20 degrees Celsius (68 degrees Fahrenheit). This speed is also referred to as Mach 1.
Aircraft such as supersonic jets, including the famous Concorde, were capable of reaching speeds beyond the speed of sound. The Concorde, for example, could fly at a maximum speed of Mach 2.04, which is more than twice the speed of sound.
In addition to aircraft, certain military jets, experimental vehicles, and rockets can also achieve supersonic speeds. It's important to note that when an object exceeds the speed of sound, it creates a sonic boom, which is a loud noise caused by the shock waves generated by the object as it moves through the air. For this reason, there are restrictions on supersonic flight over populated areas to mitigate the effects of sonic booms.
