Sonar is sound waves bounced off a object so if you are going the speed of sound the waves cannot bounce off the object and determine the speed of the object
No, it is not possible for any object or signal to travel faster than the speed of light according to the laws of physics as described by Einstein's theory of relativity. Any object that appears to be moving faster than the speed of light is a violation of the laws of physics.
Yes, it is possible for an object to be traveling with a non-zero velocity even if it is experiencing a net zero external unbalanced force. This is because the object may have inertia, which allows it to maintain its current velocity unless acted upon by an external force.
No, Albert Einstein suggested the idea of travelling at the speed of light and what would occur to physical properties, which lead him to special and general relativity. However, he never said it was possible to do so. Quite the opposite actually, he discovered that as an object travels faster and faster through space, it requires more and more energy to go even faster, to the point that if an object were to travel onward to the speed of light, it would require all of the energy in the universe to push it to that speed. It's also known as relativistic mass.
you need to know volume, because d=m\v (density equals mass over volume)
The speed of sound varies a lot, depending on the material through which it passes, and (to a minor degree) the temperature. In air, the speed of sound is about 330 meters/second, but in solids, the speed of sound can be several times larger than that. And yes, it is possible for an object to go faster than the speed of sound. Certain jet plains do that regularly.

It moves faster or slower
You cannot travel at the speed of light. Period.
To determine if an object is moving faster than another object, compare their respective speeds. The object with the higher speed is moving faster. Speed is a measure of how far an object travels in a certain amount of time, so the object that covers more distance in the same amount of time is moving faster.
Sound travels faster through dense objects.
The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.
When travelling faster than the speed of sound (supersonic speed), a sonic boom is created. This is a loud noise produced when an object passes through the air at a speed greater than the speed of sound. It can be disruptive and can lead to regulations on supersonic flight over populated areas.
The Mach number of an object travelling through a fluid is its speed relative to the speed of sound travelling through the same medium. So an aircraft flying at Mach 1 at sea level would be travelling faster than an aircraft flying at Mach 1 at a high altitude (where the air is thinner and sound travels slower). An object travelling at Mach 2 is travelling twice as fast as an object travelling through the same fluid under the same conditions (temperature and pressure). BUT In common usage, Mach 1 is the speed of sound in air, at sea level and 20 deg C.
According to the theory of relativity, it is not possible for any object with mass to travel faster than the speed of light in a vacuum, which is about 186,282 miles per second.

You can determine when an object is moving faster by looking at the steeper slopes on the graph. Steeper slopes represent greater changes in speed over time, indicating faster motion. Additionally, peaks in the graph may represent moments of maximum speed.
The plane and every object on Earth is moving relative to the the planet, we just don't notice. When the plane is travelling against the motion of the Earth's spin, it seems like it is travelling forwards, but from space it can be seen that it is travelling backwards.
