To get the speed of the Earth's revolution at the equator, you divide the Earth's circumference (about 40,000 km) by the time it takes for one revolution (about 24 hours).
That cannot be calculated without knowing the average speed over that distance.
If a satellite is in an elliptical orbit around the Earth, the Earth will be at one of the focii. The speed of the satellite will then constantly be changing. It will move the fastest when it is nearest to the Earth (perigee) and slowest when it is furthest away (apogee).
It varies greatly. It will depend on how far away it is from the object it's orbiting. If it is in a circular orbit around the Earth, its speed can be calculated by the formula: speed = Squareroot(398600/(6371+altitude)) This will give you an answer in kilometers per second.

no. it's top speed was calculated to only be mach 3.5
Average speed is calculated by dividing the total distance covered divided by the time taken. Instantaneous speed is calculated as the derivative of displacement with respect to time.
"instantaneous speed"
In 1728, James Bradley deduced that starlight falling on the Earth should appear to come from a slight angle, which could be calculated by comparing the speed of the Earth in its orbit to the speed of light. This "aberration of light", as it is called, was observed to be about 1/200 of a degree. Bradley calculated the speed of light as about 298,000 km/s (186,000 mi/s).
It is calculated as the derivative of the function describing the location of the object.
Average speed is calculated by dividing the total distance traveled by the total time taken to travel that distance. The formula for average speed is: average speed = total distance / total time.
The momentum of an object is calculated as the product of its mass and velocity (momentum = mass × velocity). While the lunar vehicle travels at the same speed of 12 km/h on the Moon as it does on Earth, its mass remains unchanged. However, since the gravitational pull on the Moon is less than on Earth, the vehicle's weight is reduced, but this does not affect its momentum. Therefore, the momentum of the vehicle will be the same on both the Earth and the Moon at that speed.
